I recently bought a 1997 GMC K1500 Suburban. When I bought it, the right front caliper had locked up and destroyed the rotor. So I replaced both rotors, both calipers, and new pads. But the caliper was still grabbing. So I thought, maybe the hub was going (it has over 200K on it). So I replaced both hubs. Still grabbing - so I replaced the rubber brake lines - and STILL grabbing - although not as bad. Sooo - I ensured that everything was installed to specifications (torque specs, resurfaced rotors, etc.) - and took it for a drive - and it seemed to be OK - pulled into a parking lot, turned left to park in a spot - - went inside for about 2 hours - came back out, and the truck wouldn't even move! Gave it a bot of gas, heard a LOUD bang from the right front - and I could move again, although it was like driving with a warped rotor - then it smoothed out and drove fine - - I'm lost as to what to do now - - I'm looking at replacing the ABS module (I tried unplugging it - no change) - but is there something I'm missing here?
