Hi all,
I have a 91 Alpina B12 5.0. The front brakes are the same as the German spec 750, 4 piston calipers. Anyway, I'm getting a loud grinding sound from the front brakes when coming to a stop. They don't grind until the car is almost stopped, then for the last few feet there is a grinding sound that can be felt and heard in the car. I've pulled the wheels, and checked the front pads and rotors, they appear almost new. The pads also seem to throw a lot of brake dust, though this might be normal. The braking performance seems fine, other than this grinding as it is coming to a stop.

Any ideas?

Thanks in advance,
