General Tech Why do my brake calipers always seize when I do brakes

[crimsonride]

So far I’ve done brakes on two F150s with 100k miles and one Chevy with about 200k...all three with a siezed caliper at some point! What am I doing wrong? I’ve used a brake pad and bar clamp to compress the pistons. New pads and rotors. Now I’ve I’m up to three trashes brand new rotors. Is there something I’m doing wrong that’s causing my calipers to seize?

My 02 Chevy just trashed the rear rotors and what I found was that the surface that the calipers and pads slide on was rusty and didn't let things move correctly.
