Deliver even, hydraulic clamping force to your brake pads with the A1 CARDONE Remanufactured Unloaded Disc Brake Caliper 18-4021 (also written 184021). A disc brake caliper presses the brake pads against the rotor to slow the wheel, and this unit is cataloged as a direct-fit replacement across a long list of GM cars and trucks — including the 1978-1989 Buick Electra, 1978-1990 Buick LeSabre, 1991-1996 Buick Roadmaster, 1978-1996 Chevrolet Caprice, 1985-2002 Chevrolet Astro, 1978-1992 Oldsmobile Custom Cruiser and 1985-2002 GMC Safari. See the Buyer's Guide tab for the full list of 35 applications.
- Durable pistons: resistant to cracking or pitting and built to handle great loads.
- New EPDM seals: rubber seals are replaced with new high-temperature EPDM rubber for extended life and consistent performance.
- New bleeder screws: provide trouble-free bleeding and a positive seal, and a plastic cap plug protects every brake port thread during installation.
- Protected finish: treated with a specially formulated rust inhibitor and kept in the original-equipment finish.
Because it is an unloaded caliper, it ships without brake pads. A mounting bracket, new banjo bolts, washers, and new stainless steel hardware clips and mounting pins are included where applicable — check your original to confirm what your vehicle uses. Remanufactured from an original-equipment core, CARDONE's process reduces the energy and raw material needed versus a new part by 80%.
