My 99 M750 sounded like a dumptruck when I applied the rear brake at anything less the 50mph, and I just couldn't quiet it. to be honest, I didn't use it that often, but when I did, it was embarassing as hell.

was it noisy because the pads were worn? if so, I hope you checked your disc. it may be scored from metal to metal contact.

NO MORE NOISE! it's quiet as a whisper, and has been that way for more than a month and 1000+ miles.

That sounds good! My experience is that new pads do not cure the sound for that long... Let's hope it stays!

I've found tht replacing the push pin with a bolt that just barely fits is the only way to "cure" the noise. I think it was a 1/4 in. allen head bolt with two nuts on the backside, I haven't heard the noise in almost 4 years now.

I've had much the same experience as Chris. changing pads seems OK for a while, but eventually the noise comes back. I've moved to a non- sintered pad which helped, but will probably wear at a greater rate, plus doesn't quite have the same perceived "grip" as a sintered one. Also, I found my rear disc undersize in thickness, and on removal from the wheel it warped really badly (radial rather than circumferential) and seemed to have been "off-centre", running more towards one caliper piston than the other. The new disc sits nice and central in the caliper, and so far (c. 5000 kms) is nice and quiet.

Yeah, i gave up and got brake tech floating rear rotor.

I consider the rear brake noise as I consider the clutch rattling .... .

Anyway, rear brake usage is at minimum anyway so when I used it, I let it sing its song....
