What This Caliper Helps Address

• Rear brake drag or uneven braking on the left side
• Leaking or sticking caliper issues
• Low brake pedal concerns tied to hydraulic caliper problems
• Brake pull during stopping caused by caliper imbalance
• Corrosion-related caliper wear on older GM brake systems

Installation Notes and Tips

Verify the GM brake code on the Service Parts Identification sticker before ordering, since fitment depends on brake-code and piston configuration. The inlet and bleeder port size is M10x1.0. Use the brake fluid specified by the vehicle manufacturer, and follow standard brake service procedures when bleeding the system. Silicone grease is used on floating caliper mounting pins.

Quality Assurance

Each Cardone remanufactured caliper is pressure-tested and rebuilt with new premium components, including high-temperature EPDM rubber seals and durable piston materials. The remanufacturing process also reduces raw material and energy use compared with producing a new part.
