Common Problems This Part Can Address

• Brake fluid leakage from a worn caliper seal or piston area

• Poor pad movement from worn slides or abutment contact points
• Corrosion or wear on an original cast iron caliper body
• Brake drag or inconsistent pedal response tied to caliper operation

Installation Notes and Tips

Verify front left position, piston diameter, and bleeder screw thread size before installation. Transfer or replace brake pads and inspect the rotor, hose, and mounting points during service. Because mounting hardware is not listed as included, confirm whether your application requires reuse of existing hardware or separate replacement parts. Bleed the brake system after installation and check for leaks and proper caliper movement before returning the vehicle to service.

Quality Assurance

Each PowerStop L6156 caliper is pressure tested to verify piston operation and inspect for leaks. The remanufacturing process uses new seals, slide pins where applicable, dust boots, bleeder screws, and stainless steel brake pad abutment clips to support consistent quality and safety.
