Product Details

Cardone 18-B4718 is part of the Unloaded Caliper w/Bracket line, a remanufactured brake caliper program focused on OE fit and service-ready construction. Each unit is pressure-tested and rebuilt with new premium components, including high-temperature EPDM rubber seals and corrosion-resistant hardware elements where applicable. The caliper is treated with a rust inhibitor and finished to retain the original equipment appearance. This part cross-references Buick 18042413 and Cadillac 18043184 for the same application.

Compatible With 2003-2005 Buick Park Avenue, rear left; 2000-2005 Cadillac DeVille, rear left; 2004-2005 Pontiac Bonneville, rear left; and 2000-2004 Cadillac Seville, rear left. For 2000-2005 Cadillac DeVille applications, GM brake code JL9 is noted in the fitment data. The Cardone 18-B4718 is also listed for vehicles with a metal piston and mounting bracket requirement in the rear left position.

Common Brake Issues This Part Can Address

• Brake drag or uneven rear braking on the left side
• Leaking caliper seals or fluid seepage at the caliper body
• Corrosion or sticking from worn piston and seal components
• Soft or inconsistent brake pedal feel caused by caliper-related hydraulic issues
• Brake noise or poor brake response from a worn rear caliper assembly

Installation Notes

Verify the vehicle brake code and rear left application before ordering, especially on GM platforms that use service parts identification labels. Use the OE-specified brake fluid listed on the master cylinder reservoir cap, and replace fluid from a sealed container only. Bleed the system thoroughly after installation, and apply silicone grease to floating caliper mounting pins where required. New pads are not included, so inspect pad condition and rotor surface before reassembly.

Quality Assurance

Each Cardone remanufactured caliper is 100% pressure-tested and rebuilt to meet rigorous performance standards. The remanufacturing process reduces raw material and energy use compared with producing a new part, while maintaining OE-style fit and service reliability for the listed Buick, Cadillac, and Pontiac applications.
