I just sent my x6m to dealer because there a very loud noise when i break my car.

The car sits in the bmw store for two days, and they just told me they cannot do anyting about it even though they changed pad, there is still a noise coming from the break.

They said all the x6m and x5m have the same problem, BMW is still trying to find a solution and there will be a recall

WTF do not know how long they want me to wait!~!!!

 

performance brakes sometimes squeak......

 

Loud noise as in what? Squeal? Clattering? Front or rear? One side or the other?

 

it is squeal, both front and rear have that noise

 

Squeal unfortunately is perfectly normal for high performance brakes. It's especially true if you mostly drive in the city where brake dust builds up more. A good hard stop coming off the highway will usually clear it up for a little while.

The only real solution is different backing plates (rare to find) or different pads.

 

thanks a lot

i am thinking to get the brembo kit, do not know if it will help

 

We have installed quite a few setups with Brembo GT kits and none of them had problems with noises. The only Brembo setup that will make noise is the GTR kit.

Let me know if I can help you out with a Brembo setup. We are a Brembo distributor and we are direct with them.

 

yup correct!!! This is normal on high performance brakes, and these are needed to slow down the big beast.

 

Definitely normal. It rreally surprised me that the x6m/x5m didn't even have slotted/drilled rotors. Crappy M brakes...Not a new story.

 

my ml63 did the same so they replaced rotors ....maybe ceramic pads?

 

i'd guess it's because of the weight of the vehicles.

 

I'd say chill and let them sort it out, Would you rather have a "BRAKING" failure due to a something that might be more worse then what it is ?.

 

I here you man...my M has the same problem and my service adviser said they are aware of the situation and trying to find a solution. Mine only squeal in reverse and now with 5k miles its not as bad.

 

could you pm me the price for the brembo kit for x6m

 

Don't agree on the crappy brakes part. The brakes on my X6M are awesome. Have you actually seen them? The front rotors are the biggest I've ever seen and the stop the vehicle smoothly, quickly and effortlessly from even hyper speeds.

Not sure why they'd need to be drilled or slotted....the X6M or X5M isn't purpose-built for the track where heat dissipation is essential...unless you're using it to tow your track car to the track.

BTW, mine only squeal when I back it out of the garage if the rotors were wet the last time I drove it. The sound is from the pads wiping off the ferrous build-up on the rotors. The squeal is gone after the first stop sign or red light.

Put up with it...it's the sound of confidence.
