My brakes are squeaking like an old garbage truck and it's really embarrassing. It's hard to look cool while coming to the stop when all the women are cringing from the loud shreak of my brakes.
I asked the dealer about this and he said that it's common for these brakes to squeak. Somehow I doubt this. They said that I should just do a few hard braking maneuvers and that after I do a few of those, my brakes should be fine.
Is this happening to everyone else? I've never had brakes before that were this squeaky before.
squeak is good. but, if you are concerned about females:
usually the squeak comnes form the vibration of the pad against rotor surface (that is if you have stock brakes). you can almost always solve this by applying an adhesive to the back of the pad. any competent shop can do this.
These are original brakes....at least I have never changed them. I bought this car as a certified series 2001 325Ci from the dealership about 4 months ago. They just started squeaking about 3 weeks ago or so and now squeak everytime I hit the brakes (light braking). Perhaps I will just start binary driving: either full gas or full brake At least that way I won't get squeaky brakes....just a few tickets :P
Squeeking can also be caused by crystallization on the brake bads. This happens when the brakes are heated to a really high temperature and cool too fast. Typically this happens to people who brake slowly and over long distances. (e.g. grannies that start braking for a stoplight 2 blocks away) The friction builds up tremendous heat.
If that's the problem, then the dealer's solution was correct. speed up and brake hard a couple times. Ideally, you want to brake late and hard all the time, but it's not practical for street driving.
