Carlson Disc Brake Caliper Piston P/N:7640
Rebuild firm, even brake clamping with the Carlson disc brake caliper piston (P/N 7689), a front caliper piston that uses hydraulic brake-fluid pressure to force the pads against the rotor. It installs as a direct-fit replacement on many vehicles, among them the 1992-2005 Chevrolet Cavalier, 1992-1996 Chevrolet Beretta and 1992-1996 Chevrolet Corsica — see the "Vehicles it fits" section for the full list.
Brakes work as a system, so when the friction material is replaced the caliper hardware is often ready for service too. If a scored, seized or leaking original piston is behind your brake trouble, this replaces it. Replacing both sides together is recommended for even, balanced braking.
Interchange: FH7689
