car sat for years. brake pads clamped or rusted to brake rotor and wheels won't move , how to remove caliper from rotor?
Hi - although the brake rotor is rusty, brake pad material is organic, and won’t really "rust" to the rotor. Remove the brake caliper bolts, and use a sturdy pry bar to leverage the brake caliper off the rotor. This may require a bit of force if the rotor is grooved, since the brake caliper piston is likely frozen in the caliper at this point. The pads may be damaged with the removal, but this is unavoidable. Pry each side a bit at the time to work the caliper off without damaging it.
