Deliver firm, even clamping force to your brake pads with the A1 CARDONE Remanufactured Unloaded Disc Brake Caliper 18-4021 (184021) — a Camaro brake caliper that installs as a direct-fit replacement for the 1978-1981 Chevrolet Camaro, 1978-1996 Chevrolet Caprice, 1978-1985 and 1994-1996 Chevrolet Impala, 1985-2002 Chevrolet Astro, and many more GM cars and trucks (see the Buyer's Guide tab for the full list).
- High-temperature seals: Rubber seals are replaced with new high-temperature EPDM rubber for extended life and optimum performance.
- Durable pistons: Pistons resist cracking and pitting and handle great loads.
- Corrosion protection: Treated with a specially formulated rust inhibitor and kept in the original equipment finish.
- Install-ready hardware: New bleeder screws provide trouble-free bleeding and a positive seal, and a plastic cap plug protects every brake port thread. New banjo bolts, washers, stainless steel hardware clips, mounting pins, and a mounting bracket are included where applicable.
As an unloaded caliper, it ships without brake pads, so order pads separately. Remanufactured from an original-equipment core, it houses the pistons and seals that press the pads against the rotor. Signs a caliper may need replacing include brake fluid leaks at the caliper, a piston that sticks or drags, uneven pad wear, or a pull to one side under braking; if a failed caliper is the cause, this unit replaces it. For balanced braking, it's good practice to service both calipers on the same axle together.
