Installation Notes and Tips

Verify the brake code, GVW rating, and front right position before ordering, especially on Chevrolet Express, GMC Savana, Silverado 3500 HD, and Sierra 3500 HD applications. Use the OE-specified brake fluid listed on the master cylinder reservoir cap, and replace fluid from a sealed container only. For floating caliper mounting pins, use silicone grease. Bleed the system thoroughly after installation and inspect hoses, pads, and rotors for wear before returning the vehicle to service.

Quality Assurance

Each Cardone caliper is remanufactured to rigorous quality standards, pressure-tested, and assembled with new wear components to support reliable brake operation. The remanufacturing process also reduces energy and raw material use compared with producing a new part.
