Q: How to overhaul the front and rear calipers on a Lincoln Mark VII?
A: Start by raising the vehicle, removing wheels, and detaching the brake hose from the caliper. Clean the caliper and use compressed air to remove the piston. Remove dust boot and piston seal, inspect for damage, clean, and reassemble with new components. Lubricate and install the piston, boot, and bolt insulators. Reinstall the caliper, connect brake hose, bleed brakes, and test operation. For 1975-1990 rear calipers, also disconnect the parking brake cable, inspect, and reinstall brake pads. Adjust the piston, reconnect and adjust parking brake, reinstall wheels, and test. For 1991-1992 Mark VII rear calipers, disconnect parking brake, remove caliper, and replace if necessary. Reinstall brake pads, caliper, and slider pins. Clean pinch bolt threads and apply thread-locking compound. Install brake hose with new washers, bleed the system.
