11 Mini Cooper Setting Off Rear Pad Warning Again After 2000 Miles
Staying Alive. Stayin Alive.
Keeping Y'all and Your MINI on the Road With Proper Brake Pad and Rotor Maintenance.
You simply won't live very long if you drive your machine without operation brakes. OutMotoring wants you lot to exist live; very alive. Lots of other people want you alive likewise. Brakes are hyper critical to keeping yous safe as you drive. Having skillful properly inflated tires, a clear windshield, and a adept dose of mutual sense can help besides, but brakes are simply something you lot cannot afford to neglect. Equally brakes clothing they keep to practise their chore. This is unlike tires which slowly get hard, lose traction, swell, crack and brainstorm to role poorly. Y'all as a driver will likely Non notice this slow wearing of the brake components because they even so function as they should until something fails. They cease working when a restriction pad wears through to the backing plate, a brake rotor wears through to the venting, a brake line leaks, a main cylinder fails, or a restriction caliper seizes or wears out. Even though modern Automatic Braking systems are rather complex the full general concept of how they piece of work is basic.
Hither's how they piece of work. You (or in this instance your pes) press on a lever. That lever is attached to a special valve (called a chief cylinder) that amplifies and distributes that force in a certain percentage between the forepart and rear brakes. Brake fluid contained within small diameter metallic pipes and hoses is pushed through special valves, chambers, lines, then into piston chambers of restriction calipers located at each wheel. This turns the pressure placed on the brake pedal into a pressure level that somewhen presses brake pads directly onto the brake rotors (the circular metal parts you can meet through the wheel) which then reduce the speed of the automobile. Wow, that is actually quite circuitous! While the braking system is more complicated than described, particularly with modern computer controlled systems that integrate traction loss, weight shift, speed, and many other variables, agreement this will get yous through a basic conversation with a technician or service writer at your local shop or as you lot navigate shopping for parts at your favorite MINI parts retailer.
So, What Do I Demand To Exist Aware Of?
The stunning, and massive, cerise John Cooper Works Big Restriction Kit Calipers shown peeking through the spokes of a wheel. In the background are the giant JCW Cross Drilled brake rotors. Hidden from view at this angle are the brake pads. Your MINI may not have these flashy red calipers or cross drilled rotors but mayhap someday it volition!
The 2 main braking organisation components that need to be serviced and replaced are restriction pads and restriction rotors. Generally brake pads last 35-50,000 miles under normal circumstances. Brake rotors typically last 40-xc,000 miles, again depending on driving conditions, terrain, driver awareness, braking compound, weight of the motorcar, and many other variables. Usually a driver tin become 2 sets of brake pads replaced earlier needing to replace the rotors (the large round apartment objects behind each wheel) when going to the third fix of brake pads. This should be carefully reviewed with your mechanic equally brake rotors have very specific thickness ratings and if you lot article of clothing across that minimum thickness bad things happen. You may need to supercede rotors more often or within fewer miles than our general range noted, only in full general they last twice as long equally brake pads.
Front and rear brake pads wear at unlike rates, depending on many variables such as the ratio of the front to rear bias in the Chief Cylinder (the first main valve that controls braking distribution). Generally cars have a 60/forty ratio or fifty-fifty college depending on weight, size, and type of car. You lot may be surprised, as I once was, to discover that the REAR brake pads in my 2003 MINI had worn out at close to 25,000 miles while the fronts lasted nearly 45,000 miles. Others observe the opposite but strange things can happen depending on driving variables.
Go on An Eye On Your Brake Pads
So, while this variable life-bridge range can be a bit confusing, the best matter to practise is to look between the spokes of the wheel at a bending and smoothen a light at the brake caliper and notice the thickness of the restriction pad material.
At some point your brake pads and rotors Will need to be replaced.

If the brake pad material is less than ?" you need to be cautious as you lot plan the next 6 months of your 'driving' life and budget accordingly. Fresh brake pads are close to i/2" thick. Bank check out the pic above. If you have significant grooves in the face up of the rotor that you can feel with your finger or actually encounter yous probable have brake pad problems or at some point the pads have created uneven wear patterns on the rotors.
A quick visual inspection is the all-time mode to monitor your brakes. Consider doing it one time a month equally y'all fill up gas in the tank.
New restriction pads are more often than not ½" thick. If your brake pads are less than ?" first planning for replacement.
What's Going on With my MINI? It Shudders When I Brake!
If you feel this shudder in the steering wheel when braking it is typically due to a warped front restriction rotor (or both) only tin also be due to worn necktie rods, brawl joints or other components. It is always best to consult a mechanic to confirm. If information technology is the restriction rotors it's a easy prepare. When metal rotors get heated up and cooled too fast they tin can warp. This tin happen as a driver cruises down a steep loma and rides the brake pedal or is constantly pushing the restriction pedal, speeding upwards and doing it once again, and over again, and again. Driving in decorated traffic with bursts of speed over and over once again can likewise practice this as would driving through a puddle after using the brakes a LOT. There are other causes for warping (such as over tightening cycle bolts) but a shudder is the most common. If yous feel a like shudder in the seat or floor area it is generally related to a warped rear restriction rotor issue. Merely replace the warped rotors with new rotors equally before long as possible.
Many years ago information technology was common to the have the rotor off the car and utilise a metallic lathe to cut the warped material off .01 of inch at a time until the surface was flat once more, after which they were put back on the auto Afterwards confirming the minimum thickness had non been breached. This exercise is a dying art as shops rarely have the fourth dimension (nor does the customer want to pay for the labor) to "turn a rotor". It is frequently much cheaper and faster to only buy new rotors and recycle the old.
Worn vs new brake rotors. Image on the left shows the internal venting exposed due to excessive vesture of the rotor surface.
Then, that's that. You need to replace warped or worn rotors as office of car ownership. If you own your car for more than ane-2 sets of brake pads you're likely going to need to replace all or at to the lowest degree a fix of rotors at some bespeak. What exercise you practice?
Each rotor has a 'minimum thickness'. Have your mechanic check yours before replacing.
Have your mechanic check the thickness of the restriction rotors to ostend they are within spec and estimate future wear as yous replace brake pads at the aforementioned time to confirm the rotors will last 'some other round'.
My Rotors are Rusty. I Must Demand New Rotors, Right?
Incorrect. While rust is a an unwanted thing it is a reality of life equally nosotros drive cars fabricated essentially of steel. And brake rotors are mostly fabricated of steel. Steel, when not treated or painted will rust. The flat part of the rotor where the brake pad makes contact tin can never exist treated to non rust but the raised area where the dorsum of the wheel butts upwardly, called the 'lid', can be painted or treated to go on information technology from rusting. Don't be concerned if after washing your car you observe your rotors are rusty. Simply grab your keys and take your MINI for a ride. A quick stomp on the brake pedal while your car is moving will fix that right upwards!
Rust spots on a steel rotor is common and unless excessive is normal.
Blinky, blinky. Warning! Brake Pad Symbol. WHAT?
The next level of warning volition be nuance lights that alert you that something needs attention. Exist on the lookout for brake related signs, symbols, warnings or words that may popular upwardly on the dash. These are important to exist aware of and empathize so you can react accordingly.
To make matters a bit confusing some motorcar manufacturers pre plan into the dash warning system when they approximate the restriction pads or other components may fail. This is based on preliminary estimates based on miles driven and average speeds, etc of your car. Recall though that some people drive two,000 miles a month on the freeway and others drive 2,000 miles a month in stop and become traffic around town. Some drivers hammer on their brakes at the last 2d and others coast to a end with gentle pressure level on the brakes. These estimates are bound to be wrong.
Each model has dissimilar symbols and warnings for estimated vs actual restriction wearable condition. Check your manual to confirm.
This estimated brake life warning indicate may display on the dash whether the brake pads are actually worn or not. This 'warning' is somewhere between 'very nice of them' to 'ridiculous' equally it makes the auto owner call up they take a critical problem and they get to the dealer right away and and so the dealer/repair shop promptly replaces the brake pads and rotors and charges you lot somewhere around $i,200. If the actual thickness of the restriction pads and rotors had been tested and measured you may accept been able to go another twenty-30,000 miles (1-2 years!!) out of your 'one-time worn out' brakes!
A Word Well-nigh Brake Wear Sensors
One thing most customers do not know is that if that trivial brake article of clothing sensor is Non tripped it can exist reused when the new pads are installed, as long as it/they are in good condition. MINIs have a single rear brake wear sensor and a front wear sensor on the right side. Forepart and rear sensors are different lengths and are model specific and so exist sure to order the right sensors. Also, the brake low-cal warning on the nuance will not automatically go away once replaced. You or your mechanic will demand to get into the service style settings (very easy -- check YouTube) to reset the warnings -- ONLY after the worn brake components accept been replaced.
You will demand to know the deviation between the actual warnings on your dash to understand which is which. Please refer to your owner'southward manual to distinguish between the various warnings, icons, and lights.
Detailed info related to brake wear sensors.
How Dare You Reuse Brake Rotors?
Some well-versed auto owners and mechanics will say to never reuse a restriction rotor when replacing brake pads. While there is some understandable reasoning to that it is more often than not ok as long every bit the rotors are within spec, and the same type of brake restriction pad is re installed. This tin can be a glace gradient of confusion as there are lots of opinions out in that location. Some will say to never switch to a new brand or brake compound (the fabric the brake pad is made of) and keep the aforementioned old rotors. Logic would lean towards the thinking that if the brake pad and rotor surfaces were somehow 'married' to each other that afterwards a few miles of use both would have worn off that very thin layer or their 'relationship' (shallow dear thing I gauge). I tend to agree with that logic, however others vehemently disagree. As long as that 'new relationship' process happens fairly apace I tin can't remember of why this would be a long term outcome.
Front vs Rear or Both? Have it Your Mode. Thank you Burger Male monarch.
Another thing to consider is the fact that the front and rear pads clothing at dissimilar rates and you could exist replacing both the front and rear brakes when in fact only 1 or the other really needed to be replaced. Nigh service writers will say y'all need new "BRAKES" which they cluster equally front and rear regardless of the actual wearable of either.
A few questions need to exist directed to the service writer such equally:
1 "What are the actual thickness of the front end and rear brake pads?"
2 "How close are my forepart and rear rotors to beingness worn out based on the manufacturers minimum thickness?"
3 "Have the Brake Clothing Sensors been tripped nonetheless?"
Asking these questions often results in a modify in your work ticket. Your bill could exist half or less of what information technology could have been without asking these fundamental questions. A educated customer is typically going to spend less on unneeded or premature repairs.
Some may say "I only want to be done thinking almost brakes and want it ALL done at the same time and so I don't take to do the other brakes in 6 months or 1 yr...or whatever the estimated actual end of life of the pads or rotors is". That's fine, merely yous'll be paying to supercede things that y'all could have safely put off for tens of thousands of miles of driving.
Doing a visual inspection to measure out the actual thickness of the brake pad material is a smashing manner to stay on superlative of service costs while maximizing product life. If you just don't do this yous volition likely get ane of 2 dash warnings at some point, one would exist the 'estimated' service interval or the actual 'your brake pads accept worn through completely' alert; this is tripped by the physical brake article of clothing sensor when the brake pads are near gone.
The most critical warning is generated when a small component called a brake habiliment sensor (that is embedded between the metallic bankroll plate of the brake pad and the actual brake pad material) is triggered when information technology touches the brake rotor. This "Brake Pad Wear Sensor" has a small metal band this is designed to fail when the thickness of the brake pad cloth gets as well close to the metallic backing plate. In one case this fails information technology will send a warning to your nuance and volition have to be replaced when the brake pads are replaced. I take found that, in general, once this Real restriction alarm is tripped you likely have one-3,000 miles earlier the brake fabric is gone and the metallic bankroll starts acting as a restriction pad which grinds into the rotor and causes permanent rotor damage and poor braking. In reality when y'all run into that light, presume yous take days to schedule a repair and not weeks or months. The longer y'all await the more at gamble yous are for complete braking organisation failure and injury.
Oh, Male child, At present What?
First, information technology is very of import to know that many retailers sell brake parts such as brake pads and rotors in a fix of two which include the left AND right side for the forepart OR rear separately. You simply cannot buy a left OR a right side ready of front end or rear brake pads. You have to buy them in a 'beam set' which is the front left and right or the rear left and right. That is how they are packaged and so y'all tin't brand a error when shopping. While some retailers will Listing brake rotors separately you lot should ever buy a matching fix of left and right for the front or rear (both if y'all need to supervene upon both at the aforementioned time). If you intend on switching brands or specifications of brake rotors or brake pads y'all should match the front and rear whenever possible.
You do non take to supervene upon front and rear brake pads and rotors at the same time, but must always supplant left and correct from the same axle at the same time. This is disquisitional.
Well, you're in luck. OutMotoring.com has tons of options when it comes to replacing worn brake pads, rotors and other components. While we could get into a very lengthy performance restriction upgrade give-and-take lets just introduce a few products to consider.
OEM, OE, Aftermarket, Operation. Homo, I'grand confused.
Yous tin always supervene upon the worn stock/OEM brake pads and rotors with the same exact part that are on your car already, but that may take some inquiry if you are not the original owner or practice not have authentic service records. Going with what the manufacturer designed for your automobile is a audio choice. We offering a full selection of every manufactory installed brake pad and brake rotor that MINI specifies.
It is very of import to confirm your model every bit in almost cases the base Cooper has unlike part numbers than the Cooper South. The JCW (John Cooper Works) models with the larger "Big Brakes" require specific office numbers too.
Store online at our website using our drop down menu to select your model and sub navigateast to the "brakes" or the "replacement parts" department and then to the "brakes" subcategory.
If yous would similar to consider using aftermarket brake pads and rotors nosotros likewise have a peachy choice of brake kits (including pads and rotors) also as pads and rotors sold a' la bill of fare. Bank check out these 2 cracking kits (linked below) as they offering a significant price savings over the factory OE (Original Equipment) parts while maintaining or increasing operation. The term 'aftermarket' includes whatsoever company or production that is anything BUT the verbal office that MINI specifies for their vehicle. That will be a box with a part number from MINIs database/parts suppliers such every bit OutMotoring.
In some cases that verbal aforementioned role is sometimes sold through other channels, merely with the name of the actual visitor that makes them for MINI. In this case it volition be chosen a OEM (Original Equipment Manufacturer). It's ofttimes very hard to find out who this company is, as MINI does not advertise "hey, you can buy the same thing from company x for ½ the price!" The next tier of product would be any product other than these 2 options and would be considered "aftermarket" as they are independent and not specified by MINI equally a partner. There is oft nothing wrong with using these aftermarket products as long equally they are made to industry standards. As such we offer many options to suit your preference, budget or functioning needs. As expected don't sell brands or products that don't friction match our strict standards.
Our "Upkeep Master" budget is a great way to save money with factory equivalent brake rotors forth with restriction pads that offer a significant decrease in brake dust. I would have no issues using these on my personal MINIs and find the price savings and ease of pick a major benefit. Plus, who doesn't like saving coin?
Our 'step upwards' Stage 1 Brake Kit: Cross Drilled + Slotted offers brake rotors with slots and holes to assist dissipate estrus likewise as brake pads that will reduce brake dust build up. This upgrade kit is still much cheaper than the factory issued restriction pads and rotors and looks amazing thanks to the slot and hole pattern on the face of the rotor that can be seen through the spokes of your wheels.
I Like Big Brakes and I Cannot Lie
There are many other braking organization options such every bit upgrading not only the brake rotors and pads but the restriction calipers (front and or rear depending on the kit), and adding stainless steel restriction lines. Larger rotors with increased surface area ever help with braking operation, as do alternating performance oriented brake compounds, and larger, more effective restriction calipers. Larger brake calipers with larger pistons (nested into the caliper) besides create more than force to clamp the brake pads to the rotor. These benefits are certainly worth because every bit you shop for restriction upgrades.
At that place is more. Detect out what the magic of a Big Brake Kit tin can do for your MINIs braking. Because these kits are engineered equally ecosystem of parts the only fashion to get the benefit of using a larger caliper or rotor will exist to buy a kit designed with matching rotors and calipers. Brake pads are besides caliper specific so it's all-time to but dive in and spend the big bux.
Here is just a snapshot of what to consider from Brembo and Wilwood.
JCW Brembo Big Brake Kit $1949.95
Wilwood DynaPro 4 Big Brake Kit $1128.95
Final Comment From Brakeland
Nosotros hope you enjoyed this basic introduction to central braking components, basic diagnostics, common failures, brake component upgrades, and performance options. We intend this to exist a introduction to braking components and nosotros hope the info shared can assist you, our customers, make informed decisions whenever new brakes are considered. Keeping you and your MINI safe is ane of our number one concerns.
When you have any questions or concerns nearly which brake related products to also consider every bit well as if a Large Brake Kit is the right option for yous we're hither to help you.
