Deliver firm, even hydraulic pressure to the rear brake shoes with the Dorman - First Stop Drum Brake Wheel Cylinder W4804. Mounted in the drum brake assembly, this rear right wheel cylinder uses brake-fluid pressure to push its pistons outward, forcing the shoes against the drum. Engineered to match the original wheel cylinder's fit, function and performance, it drops in on classic Cadillacs — the 1958-1959 and 1962-1966 DeVille, 1958-1959 Eldorado, 1965-1966 Fleetwood, 1958-1959 and 1962-1964 Series 60 Fleetwood, and 1958-1959 and 1962-1964 Series 75 Fleetwood (all engines). See the Buyer's Guide tab for the full list.
Cast iron body: with a 1 in inside-diameter bore and a 7/16-20 inlet thread.
EPDM rubber cups and boots: for long-lasting performance.
Professionally tested bores: surface-tested to provide an optimum sealing surface for the pressure cups.
Bleeder screw included (bleeder screw cap not included).
Replacing the cylinder while servicing the drum brakes is a cost-effective, straightforward way to keep the hydraulic side working correctly. Made in China.
It converts brake-fluid pressure into mechanical force, pushing its pistons outward to press the drum brake shoes against the drum. If a leaking or seized original cylinder is your problem, this replaces it.
