My son has a 94 Mustang GT that started making a grinding noise at the passenger side rear wheel. I jacked the rear end off the floor, removed the wheel, put the car in neutral and had him turn the opposite wheel. The passenger side was obviously dragging. I then had him operate the parking brake and it seems to be operating correctly. Then I had him operate the brakes and noting seemed to change. Upon closer inspection, I noticed what appears to be a caliper stuck against the rotor. Nothing seems to get it freed up.

Any ideas?

It sounds like a frozen caliper. The cheapest way out is an exchange caliper as yours has a ratcheting piston design for the parking brake and requires special service tools to overhaul.

Some of the newer vehicle you have to turn it as you push it in with a c-clamp.

I dont know if this could be the problem,but i had one a while back on my camaro that locked up and would not release and i thought it was the caliper but insted it was the hose went bad, broke down inside and would let the fluid in but not let it out to releive the preasure on the caliper, replaced the hose and all was fine again.

Good Suggestion!

Just crack the bleeder valve and see if the piston releases.

I too have seen this happen, seems like it is becoming more common.
