I have a 500i with just over 1000 miles. My front breaks squeek like crazy. How do I stop the squeek? It is embarassing.
-
depending on the pads, seen sum that squeek from day one.... you can go to parts store and get a can of "brake quiet"...blue can, contents blue also.. its like spray paint for brakes...lmao thats helped me before....

Remove the pads/caliper, and coat the slider part of the bolt, with aluminum based Anti Seize. Coat the backs of the pads with a thin skin of copper based RTV (gasket maker). when the rtv is cured, 1 hour or so reassemble using blue Lok Tite on the bolt threads. I do that on EVERY brake job I do. cars/scoots/4x4's what have you
-
I hadn't thought of the RTV on the back of the pad, does that act as an absorber of the vibration?
-
Eggzactlee! The minimum amount of copper also acts as a lubricant. much the same as Lead used to in gasoline. the "squeel" is primarily an oscillation caused by parts "sticking" and not form the pad/rotor contact, as in if the parts can move the pads pull away from the rotor. The anti seize allows the caliper to float, and the rtv creates a buffer between the pads, and the caliper. The Brake quiet Batman suggested is another product that works. I have used it, and alot of aftermarket brake kits will have a tiny tube of it w/ new pads. The key ingredient is the same as rtv, silicone! If you do the sliders w/ anti seize, there is not much of a difference between the two.

hmm...never tried it... sounds like a good idea...
-
All you need is a 99 cents envelope of brake disk lube from Advanced Auto
Just put a little on the back of the pads where the pistons hit. Be careful not to get any grease on the front of the pads.
Thats it! Squeak GONE.
The chirping is the pistons hitting on the back of the pads. A bit of grease quiets that right down.

I think I just learned some really good things here. :) I hadn't even seen this topic before and certainly didn't know these things. Thanks all and scosgt.

It is amazing how much information is around here.
