ACDelco Gold (Professional) Reman Loaded Calipers come with brake pads already attached – no assembly is required. These premium aftermarket reman loaded disc brake calipers will provide the same performance, durability, and service life you expect from ACDelco.

Features:
  • Pressure tested to ensure safe and confident braking
  • Ethylene Propylene (EPDM) rubber components provide superior resistance to heat, corrosion, and leakage
  • Cast iron and aluminum specifications; no extra stress on the brake boosting mounting
  • Pre-lubed and loaded with quality friction pads for smooth operation
  • Includes bleeder screws, copper sealing washers, hardware, and mounting brackets (where applicable) for easy installation
Installation Tips
  • Always inspect brake pads and rotors when replacing your calipers. Faulty calipers can lead to uneven pad and rotor wear
  • Inspect or change brake hoses when replacing the caliper. Worn or damaged hoses should be replaced to prevent brake fluid contamination or loss
  • Use a Brake Fluid Tester to test your brake fluid. If your brake fluid has moisture in it, flush the system before installing the new caliper
  • Apply Blue Threadlocker to caliper bracket mounting bolts to lock the bolts in place and prevent loosening or backing out
  • After installing the new caliper, bleed your brakes to ensure no air is trapped in the brake fluid. RockAuto offers a selection of Brake Bleeding Tools to help with this process
  • After the brakes have been bled, top off the master cylinder reservoir with the proper Brake Fluid
