I'm in the process of converting from drum to disk. One caliper fits great, the other is so tight sliding it on that it jams the rotor.
It's like the pad is not in the caliper correctly, yet I know that it is. Ive done a lot of disk brake jobs, but never had to sand down a pad to get it to go over the rotor.
Any suggestions as to what could be wrong.

New part are, rotor, pads, calipers, bearings, seals, bolts.
Reconditioned parts are spindle and caliper bracket.

thanks
Dave

Depending on what type of disc and rotor you have. If you have the 2 peiece (like the corvette) and depending on what side you need clearence. You can shim behind the rotor to move it out alittle. Or and a washer between the spindle and caliper to move the caliper out.

To confirm or rule out the calipers being the problem.Compress the good side so the piston is completely in,then measure the distance from inboard pad to outboard pad.Once youy have a known good measurement as a reference ,measure the bad side.Rebuilt parts store calipers can sometimes be defective or wrong piston right out of the box.
Also do the guide bolt sleeves move easily in the caliper?

I'll check it out.

Dave </font>[/QUOTE]Always re-do the slides when doing disc brakes. Buy the little kit with the seals, o-rings, or whatever depending on type. Pull the pins clean them up, replace if rusted or pitted and lube properly during reassembly. If the caliper can't float freely you'll be replacing the pads again in no time.
