Hey guys, I've worked on a wide range of Bimmers ranging from all age 3 series to 7s as far as brakes go, but right now I'm having a problem with my friends 325. Did all four of his brakes, OEM parts, but after about an hour of driving the rear brakes begin squeeling, obviously somethings going on with the brakes but just wanted to know if anyone has had the same problems in the rear. Is it some what of a common thing? The fronts are fine so the whole thing is confusing me.

I have the same problem with new brakes on my 325i. I took the car to the dealership twice and both times they said it's within specs and nothing they can do about it. WTF?

imho: their mechanics suck.

stock pads and stock rotors on e46 do not squeal. all you need is proper application of an adhesive compound to the back of the pad. the squeal is caused by the vibration of the pad in the caliper.

non-stock bets are off.

Sounds like pad vibration. Pull the pads and coat all metal to metal (not pad material) surfaces with an anti-squeal compound (there are many, but I like the CRC Orange stuff), let it sit until tacky and reinstall pads.

Unfortunately that spraying the anti spueel compound on the pad has been tried. It goes away for about 2 or 3 hard braking applications but comes right back...

not a spray!!!. tube of goo.

try new set of pads. sometimes the backing plate is not cut to spec, and "walks" in the caliper.

AMEN to no spray, what you want is a tube or bottle of a plasticky like material. Look fo the ORANGE sticky material (I believe it is made by CRC and comes in a short plastic bottle with a long neck and cut off top). Spread on liberally, let set up until tacky and then put pads back in. I use this stuff and it does not go away.
