Description

Bring the rear right drum brake back to proper working order with the Dorman – First Stop Drum Brake Wheel Cylinder (W49681), a direct-fit replacement engineered to match the fit, function and performance of the original cylinder on select 1967–1973 Chevrolet and GMC trucks, vans and Suburbans. Mounted at the rear right, it converts hydraulic pressure from the brake line into the outward force that pushes the drum brake shoes against the drum.

Cast iron body: built around a 1.125 in bore that is surface-tested to give the pressure cups an optimum sealing surface.
EPDM rubber cups and boots: made with high-quality EPDM material for long-lasting performance.
Bleeder screw included: the bleeder screw cap is not included.
7/16-24 inlet thread: with a 7/16 in thread diameter for the brake line connection.

Signs this cylinder may need attention include brake fluid weeping behind the rear tire, a soft or spongy pedal, or uneven drum braking; diagnose the cause first. If a leaking or seized rear right wheel cylinder is the cause, this unit replaces it. For balanced braking, inspect and service the opposite side at the same time. Package contents: 1 drum brake wheel cylinder. Country of origin: China.
