Restore firm, even drum braking on the front-left corner with the Dorman - First Stop Drum Brake Wheel Cylinder (P/N W51086). It drops in as a direct-fit, front-left replacement for the 1965-1970 Chevrolet Bel Air, Biscayne and Impala, the 1966-1970 Caprice, and the 1969-1970 Brookwood, Kingswood and Townsman.
Mounted on the brake backing plate, the wheel cylinder converts hydraulic pressure from the master cylinder into the outward force that pushes the brake shoes against the drum, then lets them retract when you release the pedal.
Hydraulic actuation: internal pistons extend under brake-line pressure to apply the shoes, helping deliver responsive drum braking.
Front-left fit: cataloged for the front-left position on the listed applications.
Signs it may need replacing: brake fluid seeping at the backing plate, a soft or spongy pedal, or grabbing/uneven drum braking. Diagnose the cause before replacing, since these signs can have other sources.
