my squeaky brakes are driving me crazy!!

I have carbon brake pads, the previous owner put them on, supposedly they are low dust, but they do stop amazingly. They are just too dam SQUEAKY! everyone is looking around for a bus or a freight train, and they just see me in my clean M3 and they are like WTF u need new brakes.

All my friends break my chops that i need new pads but they have like 80% life left. I was told anti-squeak will not work well with these and only temporarily if it does. Does anyone have an suggestions?

The hotter they get the squeakier, like after i stop to get off the highway, they are squeaking like crazy. The only thing that helps is stopping short rather than easing into the brake pedal, but i live in an area easing into brakes is an everyday thing. Any suggestions?

i have stock break pads/rotors. They squeak too. I was told this is caused by "glazing" of the brake pads. One method was to do quick panic stops to rub it off. Or you'd have to take off the brakes and sand off the glazing.

I've just gotten used to it. Mine don't squeak that bad.

I have the same problem with my pads. When I got my discs and pads replaced they recommended Textar because I wanted something good with low dust. Bad choice, It works pretty good but I cant live with the squeak. It does it after a little hard driving similar to yours, and the quick stops also help, but it's really annoying. I think I'm going to change my pads after I check em out. It's probably due to the glazing too, but before that I had some Autozone pads that were really low dust and worked pretty good with absolutely no noise at all!

Did any of you guys that are having a squeaking problem perform the proper pad/rotor break-in procedures, per the pad manufacturer?

I've been told by numerous techs, that's what you get with Euro cars. My '08 A4 did the same thing. The techs at Audi said it's normal. Sure enough the M does it too.

Some pads can take over 500 miles to bed in, depends on a lot of things. You have to avoid hard breaking, which I know can be difficult to remember/avoid, until then. Others you can bed-in after about 15 minutes, it's really important to read the instructions that came with the pads, or check on the internet. Once properly bedded, most pads nowadays will not squeak loud enough to raise any eyebrows. Btw, the reason people make wise cracks about needing new brakes is because squeaking breaks used to indicate exactly that. There was a metal piece, called a squealer, that would come into contact with the rotor once a certain amount of wear occurred. It would give you a real nice squeal everytime the breaks were applied.

The OP has carbon brake pads, which are technically track/autocross brake pad material designed to take very high heat and stop extremely well under hard braking as in the aformentioned events. I highly doubt you will ever get them to shut up. It's just the nature of the beast. If you want no squeak, you're gonna end up changing pads IMHO. Chas

+1, performance pads are more likely to squeak due to the materials used in the pad composition.
