Detailed Description

This Cardone Ultra disc brake caliper is remanufactured to match the original equipment design for select Buick, Cadillac, Chevrolet, GMC, Oldsmobile, and Pontiac models.

This part cross-references GM OE numbers 18005264 and 18012308 for the same application. It is a strong match for long-tail searches such as front left brake caliper for 1985-2002 Chevrolet Astro, front left caliper for 1985-2002 GMC Safari, and remanufactured brake caliper for 1978-1990 Buick LeSabre.
