Brake Squeal: 2003 330ci

Hey guys,

I searched all over and haven't found anyone else that has this same problem.

Car: 2003 330ci with ~65k miles

After driving for a while each day when i apply the brakes a horrible noise is heard. It sounds like those older cars that barely run and you can hear the awful squeal from blocks away. I took it in to get it checked and they said they couldn't find anything wrong and couldn't replicate the noise. This only happens after driving for about 10min in the city and then its almost like a certain point that the brakes touch is the only time the sound is heard. Does anyone know what this problem is? If it helps, heres a diagram that shows where the sound is heard relative to the pressure applied.

Least {___|xxx|_________}Most

Thanks in advance.


Also, what would be the cost to fix this problem?

Did someone change pads and not rotors? Sometimes when that happens the new pads wear according to the groves in the rotor and "sing" when a certain amount of pressure is applied to the pedal.

If it continues you might want to consider applying an anti-squeal compound. They make the world of difference sometimes.

These synthetic lubricant contains real ceramic solids for extreme performance under the most critical braking conditions.
