I did some work on my car and it involved removing the front calipers. I couldn't believe what I saw. They were bent! Apparently they are to weak for highpressure systems like my HydraBoost combined with a S-10 M/C.
I haven't noticed any problems with the brakes, up until now they have worked. I have to admit that they have got a fair share of abuse.
Look at the picture to see tha angle they now have. I didn't see any cracks or so. They would have held up a while longer.
I will now change to C5 Calipers which are much stronger.
