Rebuild a leaking drum brake wheel cylinder and keep the hydraulic force that presses your brake shoes against the drum with the Dorman - First Stop Drum Brake Wheel Cylinder Kit 3600. It drops in as a direct-fit rebuild kit for front or rear drum brake wheel cylinders across hundreds of classic applications, including the 1969-1972 American Motors Ambassador, 1959-1972 Buick Electra, and 1962-1968 Cadillac DeVille — see the Buyer's Guide tab for the full list of 718 applications.
Inside a drum brake, the wheel cylinder converts brake-fluid pressure into the outward motion that pushes the shoes against the drum; its cups and boots wear over time and the cylinder can begin to leak. If a worn wheel cylinder is the cause of fluid seepage or a spongy pedal, this kit supplies the cups, dust boots, and seals to service a 1 in bore cylinder. Country of origin: China. Manufacturer part number 3600.
