(You save)
Keep your rear drum brakes applying firm, even pressure with the Dorman - First Stop Drum Brake Wheel Cylinder W37631. It installs as a direct-fit replacement for the 1980-1983 Toyota Pickup [All], which uses two rear wheel cylinders — order 2 for a complete rear-axle service. Mounted in the rear drum brake assembly, the wheel cylinder converts hydraulic brake-line pressure into outward force that pushes the brake shoes against the drum.
Direct replacement: engineered to the original wheel cylinder's fit, function and performance on the listed applications, then manufactured and tested for quality assurance.
Cast-iron body: 0.813 in inside-diameter bore, surface-tested to provide a sound sealing surface for the pressure cups.
EPDM cups and boots: made with high-quality EPDM rubber cups and boots.
Hardware: bleeder screw included; bleeder screw cap not included. Inlet thread size M10 x 1.0 (10 mm, 1.0 pitch).
Servicing the wheel cylinder while the drum brakes are apart is a fast, sensible way to help keep the rear brakes working properly. Signs this part may need replacing include brake fluid seeping at the cylinder or inside the drum, a soft or sinking pedal, and uneven rear braking; diagnose the cause before replacing. Country of origin: China.
