Use the brake fluid specified by the vehicle manufacturer and verify the reservoir cap or service information before bleeding the system. Floating caliper mounting pins should be lubricated with silicone grease, and new fluid should always come from a sealed container. If the vehicle uses rear drum-style parking brake components, inspect them during caliper replacement to avoid repeat brake complaints.

Quality Assurance

Cardone remanufactures this caliper using new premium components, new EPDM rubber seals, and new stainless steel hardware clips and mounting pins where applicable. Each unit is pressure-tested to confirm brake performance, and the remanufacturing process reduces energy and raw material use compared with producing a new part.
