Noise when braking, and it's not the pads
 
Hey guys,

I had a quick question- Whenever I'm braking and I happen to drive over a bump in the road or anything, I hear a "RRRRRRR" noise. It's not a squeak or anything. It happens only when I'm coming to a stop and if there's some kind of obstruction in the road, when I drive over it while braking my car makes a kind of sounds that can only be described as "RRRRRRRRR" and the braking pedal seems to go in a bit deeper.

Is this normal? It doesn't seem like it would be. Has anyone else experienced this? I have a 2002 M3, around 45K miles. I don't think it's the brake pad, and am kind of stumped.

Thanks in advance.

Brake fluid is full. Doesn't seem that that's it.

It's not impossible for it to be the pads, so unless you have visually inspected the pads in the calipers, don't rule them out.

Sure it is not just the antilock kicking in on the one wheel that hits the bump, etc.? That would explain the noise and the pedal drop. Different from when you slam on the hooks and 2 or 4 wheels go into antilock, which will cause a bigger pedal drop and more noise.
