My X3 is closing in on 40,000 miles and I have not needed any brake maintenance per the computer's estimate. It says I still have some 30k miles for front and about 13k miles for rears!

Are other people experiencing the same thing?

X3 30d here. Currently around 15 months and 20.000 mls. Computer says front brakes can go another 43.000 mls, but the rear ones need maintenance in 3.500 mls.

I had to replace my front brakes at 15,000 miles. You guys drive so much! I'm at 18 months and 17500 miles.

I would hope to get at least twice as many miles on the brakes. You must stop a lot .

I think he lives in the city

My brakes have just started to squeal when I come to a stop. It's quite loud and annoying. Car has ~10k miles on it. (I too live in the city)

Brake squeal could have a number of causes but not necessarily worn brakes. One of my C300 rear brakes was unusually loud at only perhaps 5K mi. There was plently left on the pad. As a precaution, the dealer replaced brake pads and rotors on both rears under warranty and they were silent from that day forward to 40K+ miles, when I still had a lot of pad left on front and rear.

In fact I believe I've seen you around before. White M-Sport, yes? Whereabouts in Lincoln Park?

Yea. I am going to have to take it to the dealer at some point. Just for them to see if there are any problems.

I forgot to say, first the MB tech replaced the pads. When he wasn't satisifed with the result, he didn't even ask me and changed the rotors too. It was done in one visit, so I didn't need to come back. I'm not saying that's your case but they should be able to correct it. I would not accept "it's normal".

Isn't it unusual for rear brakes to wear faster than the front ones? I thought the front brakes did most of the work.

Performance control uses the rear brakes to help the car corner better... Sort of improves cornering on the cheap.

Cruise control and Xdrive (like previously mentioned) make heavy use of the rear brakes.

Dynamic Stability Control does that and is standard. Performance Control uses more aggressive torque vectoring dynamics in addition to DSC. It's really about your braking habits and where you drive the most.
