I don't think it is a pressure problem and I doubt the braking force is that much... not that can crack metal on its own anyway. I think heat is more of a factor here prof.

I also think the stock wheel may not give a lot of cooling to it. I really dunno. I only found in my car when going from stock rim to a wider wheel base sports rim I have lower track temp... but I have AP racing caliper at the same time.... so dunno again.

But my theory on what happens to WAY is overheat over a period of time, crack after metal fatigue.
OH I like AP racing?`I can't find any AP racing caliper for 135i what the part number is?? and will it work with the brake sonser??
any picture??

thanks
