Dorman - First Stop Drum Brake Wheel Cylinder P/N:W1012
$56.99
Turn brake-line pressure into shoe-clamping force with the Dorman First Stop Drum Brake Wheel Cylinder W1012. Mounted at the rear drum brakes, it converts hydraulic pressure from the brake line into the outward push that presses the shoes against the drum. It's engineered as a direct replacement for the original wheel cylinder on the listed Dodge trucks: 1948-1949 B-1, 1948-1950 B-2, 1951-1952 B-3, 1953 B-4, 1954-1955 C-1, 1954-1956 C-3 and 1956 C-4 (engine: All). See the Buyer's Guide tab for the full application list.
- Cast-iron body: the bore is surface-tested to provide an optimum sealing surface for the pressure cups.
- EPDM rubber cups and boots: high-quality sealing components for long-lasting performance.
- Bleeder screw included: ships with a bleeder screw; the bleeder screw cap is not included.
- Key specs: 1.75 in bore inside diameter with a 1/2-20 inlet thread (1/2 in thread diameter).
Each listed application uses two wheel cylinders (one per side). This listing is for one unit (package contains 1 drum brake wheel cylinder); replace both sides together as a matched pair for even, balanced braking. Country of origin: China.
