ambient temp has no effect at all on brakining temps. average pad/rotor temps are 400f+. so a few degrees difference in ambient temps make zero difference.

if the caliper is not releasing, then the caliper slider pin or caliper itself is faulty. It will need to be replaced & should be under warranty.

if you wear the pad friction material away to the backing plate, the metal plate will hit your rotor & score the surface resulting in damage as well as horrific inability to actually slow/stop the vehicle.

 

Its a common problem for the R60 to have incorrect CBS data for the brake sensors, 15k miles on the brakes? I would bet that you do into the dealership and they just reset your cbs data. BTW the inside pads usually wear quicker then the outside pad, this is not a caliber issue or anything dramatic...its normal for these cars.

 

What makes you say thats its a common problem for the r60? I haven't seen anyone else here report it yet.

 

what is the prod date of the OP?
I see that there was a prod split on the front & rear pads. The rears were 7/11.
The rotors stay the same. the pads differ. likely a slight design change.

 

I think it is good that you are concerned about your car. It is good to ask questions so that you are informed when you are talking with the dealership.

I think we can all agree that most braking happens on the front not the rear. However, is it any different on an ALL4? I really don't know.

As others have said, driving style etc will impact lifespan. The rotors should rust up but the pads should wipe it back off once you are driving.

The wear sensors are located on the axle side of the rotor. One on the front and one on the rear. It is possible for one side of a set of pads to wear more quickly than the other.

I just did mine on my R56 and I had uneven wear on mine. I also drove another 3000 miles after the sensor tripped as I inspected my pads and there was plenty of pad there.

If you are under maintenance plan, or if you are not the type to DIY, just take it in..... The dealer will handle it.

 

What do you mean by the production date of the OP? the built date of my ALL4S?

Feb 2011 Built countryman S all4.

 

^
well, the prod date for the OP. or anyone that may be having wear issues. I'm saying it may be attributed to the early production cars? IDK.
but there is a production-split for the rear pads. It 'might' be that those posting in this thread w/ premature wear have the early prod. versions?

That may or may not even be attributed to the issue, but there def. was a change from MINI in July 2011 builds.

 

on my second set 27,000 on car. Could be the size and weight of the cm?

 

Just spitballing here, nothing very helpful to contribute, only to mention driving down residential streets how often I see people rolling down the street for a block or even two with their brake lights on. They just coast along with their feet on the brake pedal. It isn't all that uncommon and is a very poor habit to get into. How many people on car forums of all stripes with low milage brake complaints may be doing something like that without even thinking about it? Of course that doesn't take into account the horrific stop and go in the big cities which I avoid like the plague.

 

That used to be true, especially so with FWD cars. On FWD race cars that I road raced from 1988-1999 I would usually replace front pads about every 2nd or 3rd race weekend, and rear pads ... NEVER.

Many newer cars have electronic brake force distribution systems, unlike the simple mechanical proportioning valves on older cars. In very light brake applications, these electronic systems can send most brake force to the rear brakes. This saves the front pads and keeps them cool for hard stops. Harder braking demand then switches most force to the front brakes. I know newer VW's have this system and I would bet that Minis have this as well.

 

Got my Mini in for a service. I'm told that all four pads are worn out. The fronts are more worn than the rears. However the rear brake pads sensor lit up instead of the front pads which are more worn out than the rear. Probably a sensor malfunction I was told.:thum bsup:

15000miles, all four brakes are gone! oh btw, my mini is almost a year old now... does that contribute too?

 

The stock pads are by TRW, they are OEM for quite a few applications. Def not a performance pad but not garbage either.
It's quite possible the electronic gizmos are kicking in a bit too early & often on the CM, thus using the rear brakes more often.
15K is an insanely fast wear rate. 40k minimum is the norm

 

Assuming the brakes are working correctly, pad wear is directly attributable to number and intensity of brake pedal applicatons. Time and mileage are only indirectly related. If you drive in heavy traffic, and/or take many brisk drives on twisty, hilly roads, and/or do track driving, you can expect short pad life. If you drive a large percentage of the time on relatively flat, strait highways with moderate traffic, you will get very long pad life.

 

I had my all-4 for a year now and today I went in for warranty work on something and the dealer told me I need to replace the front brake rotors and pads soon, It has 19000km and only 20% left. Is it normal? And they want CAD$600+ for that. He told me R60 you must change the pads and rotors together.

 

I would think that being only a year old that it would be covered under the maintenance and or warranty!?

 

Replace pads and rotors!!! You are kidding me? Find another dealer. Additioanlly the car barely has any miles on it. They should be replaced under warranty! Sounds like brakes may be dragging if they really need to be replaced that early.

 

I have 17k on my ALL4 and just got the front pad replaced as my service light came on. The notes said the rotors where still within spec so they didn't replace those. Seemed early but whichever warranty covered it.

 

I am in Canada and I dont think the warranty here will cover it. I might try another dealer and see what they say. We only have 2 dealers around here in Vancouver.

 

is it within 12k/12months? If so, In my experience, it is covered, if nits past either, its not. It's a wearable item.

 

On my former MINI the rear brakes needed replacing sooner than the fronts. So I think that's typical for these cars. Additionally, that car had its brakes and rotors replaced at it's 1st service. In the 7 years I owned the car I had the all the brakes and rotors done twice and then last fall I did just the rear brakes and rotors.
