Hi,
my rear brake pads have worn before my front ones at only 11000 miles. Has this happened to anyone??
At first i though it was the fronts but when i checked the sensors it was the rear that had been activated first.
Mine went at 16,500 miles, no problem with the fronts so far. I was also told that the rear discs had gone from the original 10mm thickness to 8.5mm leaving 0.5mm before they need changing. Which should happen around 22,000 miles.
Neither my dealer or BMW UK seem at all concerned at this excessive wear. Nor do they offer any reasons.
Mind you they did flash the ECU.
I've never had a car do this before and have had a few "performance" models with all rounds discs.
I'll admit I am a bit of a late breaker which may cause premature wear, but surely not so oddly balanced front to rear.
My car suffers quite badly from the stumble/yoyo/bog down I've recently come to wonder if there could be a connection. I'm hoping there is a fixable fault, I find it hard to believe I'll need new rear discs before my second service.
The brake bias is set up in the MINI to favour rear over front. I know that sounds kinda strange but bear in mind that BMW only produces RWD cars. The MINI is the only FWD they make. By setting the bias towards the rear, a heavy braking situation with greater rear bias than front will help to counteract understeer, a common characteristic of FWD vehicles.
I do agree 11,000 miles sounds very strange though. I'm still on my first set of rear pads at 36,000 miles with 2.5mm left of pad before they need replacing (according to the dealers when it was serviced 4 days ago). But I don't brake late...Maybe that's a factor.
I wouldnt be much of a late breaker apart from about 2000 run miles, the rest of my driving is city driving.
I changed the fronts also but there was abit of life still in them.
The bias towards the rear does make alot of sense, so maybe its a bit to do with that
From what I understand doing numerous searches on these forums, the brake bias is still predominantly to the front.
The figures I remember are 65% front 35% rear.
Surely anything under 20,000 miles for the rears has to be suspect. Fronts going early I wouldn't question, I'd put it down to my driving and move on. Rears just seems wrong.
I give you a quote I found the other day
"a car which is severely rear biased will be a scary, twitchy ride resulting in a bad case of the white-knuckle syndrome. Envision an imaginary co-pilot yanking up on the park brake handle in the middle of every corner, and you begin to get the idea"
Probably a stupid question but are the rear pads the same compound as the fronts? Could they possibly wear quicker because they aren't as high quality?
Does anyone with aftermarket pads have the same issues? If not it could indicate that the mini rear pads simply aren't as good as the front!
My rears ran out before my fronts - BMW weren't at all worried by this, said it was 'normal'. The pads are a lot thinner on the back. Mine went at about 18500 (JCWS). When the sensor came on I actually went and bought front pads. Took them off, fitted new ones, then couldn't get the light to go off. Thought then to check the rear - never had rears go before front before. So then had to buy rear pads as well.
probably a good idea to change them all at the same time though....
