[QUOTE="Bill Koonce, post: 946079, member: 68938"] Welcome! :welcome: I'm a seasonal driver (summer car, winter car), so I'm accustomed to rotor rust and other storage related problems. Your problem does seem far more extreme than the worst rusting that I've ever encountered. My half-baked suggestion is to inspect the brake pistons for leakage and other odd-looking stuff. You might find a damaged seal, which has let in debris that's causing the piston to stick. Or the piston itself may have become deformed (usually by a bad brake job), keeping it from moving freely. You'll need to remove the caliper and pads to see the piston working. This is a good time to examine the pads and rotors (or shoes and drums) for abnormal wear. BE SURE TO USE A C-CLAMP AND A BLOCK OF WOOD TO KEEP THE PISTON FROM POPPING OUT COMPLETELY! Look for pistons that don't come straight out, and don't retract easily. As a rule of thumb, if it looks wrong (torn seal, galling and/or improper movement of the piston, uneven pad wear etc.) it probably needs to be replaced. OTOH it might be some strange ABS problem...good luck! [/QUOTE]
