thanks Dad. I don't ride my brakes, thank you very much. It's kind of insulting when someone who doesn't know you talks down to you like that, but I'll let it go.
I know bimmers have poor brakes in the wear department. I think I just got a bad set of pads really, and they didn't hold up. I mean, I just replaced them last summer, and I replaced the rotors, with stock stuff (for dirt cheap). You get what you pay for I guess. The pads dug grooves in my rotors, so they had to be replaced as well. But I wondered if anyone had experience with the copper bushings in the calipers. Seems to make sense in theory that rubber bushings would do a worse job, but is it really worth $120?
Anyway, thanks for the input all.
