Keep the hydraulic side of your brakes working with the Carlson Disc Brake Caliper Piston 7569. The caliper piston uses brake fluid pressure to force the brake pads against the rotor when you stop, making it a vital piece of caliper hardware. It fits the front or rear position on a wide range of medium- and heavy-duty commercial trucks, including the 1980-1990 Chevrolet C60 and C70, 1988-1991 Chevrolet B60, 1984-1994 Ford F-600, 1984-1993 Ford F-800, 1993-2000 GMC B7, and 1987-1999 Isuzu FSR — see the Buyer's Guide tab for the full list of 56 applications.
Brakes are designed as a system, and industry brake service experts agree that when the friction material is ready to be replaced, the hardware is too. If a scored, seized, or leaking original piston is behind your brake trouble, this is a direct-fit replacement for the listed applications.
