Hello again.

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

You might just require new pads probablly, not sure though, maybe even a C-Clamp could do the trick? Not sure though, it all varies on the problem at hand.

If you can, I would get a second revision done by another dealer if troubleshooting doesn't work out'

Good luck man!

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.

What a way to wear out the pads...
Is this true by any means?

I've never had any glazing problems and I drive like a freaking maniac, stock rotors and equipment. I dont know what pads I have on this time, someone else did them.

Yeah I notice that alot too when I'm driving new/customers vehicles. It is normal for them to do that. I don't know why....but that's the way they were made.

To stop squeaking, try look for a mechanic to machine your discs, and if necessary change the brake pads.

Shouldn't this have been done as part of the BMW certification process my car 'apparently' went through? I guess they didn't do it so I would have to pay for the service coming up in 10000km more.
