I had installed the d52 calipers on my 71 blazer 4wd. I Think They work great when they work. My issue is that my one caliper seems to be partially seized. I can move the piston in with a C clamp. When I install it back on and step on the break, the caliper will not release from the rotor once I release the pedal. Any ideas on why this is happening? Thanks, Mike
