Description

Bring hydraulic pressure back to the rear drum brakes with the Dorman - First Stop Drum Brake Wheel Cylinder W4803. It installs in the rear-left position as a direct-fit replacement for the 1958-1959 and 1962-1966 Cadillac DeVille, 1958-1959 Cadillac Eldorado, 1965-1966 Cadillac Fleetwood, 1958-1959 and 1962-1964 Cadillac Series 60 Fleetwood, and 1958-1959 and 1962-1964 Cadillac Series 75 Fleetwood (all engines).

Inside the drum, this cylinder receives fluid pressure through the brake line and pushes the shoes outward against the drum. If a leaking or seized original cylinder is the cause of a soft pedal or fluid behind the drum, replacing it while servicing the drum brakes helps restore proper hydraulic action.

Cast-iron body: 1 in bore with a 7/16-24 brake inlet thread.
EPDM rubber cups and boots: made with high-quality EPDM for long-lasting sealing.
Professionally tested: the cylinder bore is surface-tested for an optimum sealing surface for the pressure cups.
Bleeder screw included (bleeder screw cap not included).

Country of origin: China.
