Dorman - First Stop Drum Brake Wheel Cylinder P/N:W3677
Deliver reliable hydraulic force to your drum brake shoes with the Dorman First Stop Drum Brake Wheel Cylinder W34151. This front-left wheel cylinder installs like the original unit on the listed applications, dropping in as a direct-fit replacement for the 1960-1964 Chevrolet Bel Air, 1960-1964 Chevrolet Biscayne, 1960-1961 Chevrolet Brookwood, 1963-1965 Chevrolet Corvette and 1960-1964 Chevrolet Impala (All engines).
Inside a drum brake, the wheel cylinder converts hydraulic pressure from the master cylinder into outward force that pushes the brake shoes against the drum. Replacing the cylinder while you service the drum brakes is a quick way to keep the hydraulic side of the system sealed.
If a leaking or seized wheel cylinder is the cause of a soft pedal or fluid on the shoes, this replaces it.
