Mercury YW1Z-2552-AA Caliper With Pads

Reconnect the brake hose, bleed the brakes if necessary, install the wheel, lower the vehicle, tighten lug nuts, pump the brake pedal to engage the pads with the disc, and test the brake operation before normal vehicle use.

To overhaul the front calipers and 1989 and later Town Car rear calipers, start by raising the vehicle, supporting it on jackstands, and removing the wheels. Disconnect the brake hose banjo bolt and detach the hose from the caliper, ensuring no air enters the hydraulic control unit on ABS-equipped models. Clean the caliper exterior with brake system cleaner and place it on a clean workbench. Use compressed air with caution to remove the piston from the caliper and proceed to remove the dust boot and piston seal. Inspect the piston and caliper bore for damage, corrosion, or wear. Clean all parts with brake system cleaner and reassemble with new seals, bolt insulators, and caliper bolts if necessary. Lubricate with brake fluid and install the piston, dust boot, and caliper bolt insulators. Finally, follow the caliper installation procedure, connect the brake hose, bleed the brakes, and test the brake operation before placing the vehicle into normal service.

Reassemble the caliper with new parts, ensuring proper lubrication and positioning of seals and boots. Check the piston fit in the bore and install the bleeder valve securely.
