Restore firm, even rear-drum braking with the Dorman - First Stop Drum Brake Wheel Cylinder W37420, a direct-fit rear wheel cylinder built for the 1979-1990 Toyota Pickup, 1991 Toyota Pickup, 1992-1995 Toyota Pickup, and 1991-1997 Toyota Previa (engine: All). Mounted in the rear drum brake, the wheel cylinder converts hydraulic pressure from the brake system into outward force that pushes the brake shoes against the drum, so a leaking or seized cylinder is a common reason to service the rear drums.
- Quality materials: made with high-quality EPDM rubber cups and boots for long-lasting performance.
- Cast iron body, 0.875 in bore: the wheel cylinder bore is surface-tested to provide an optimum sealing surface for the pressure cups.
- Hardware and thread: bleeder screw included; bleeder screw cap not included. M10 x 1.0 inlet thread (10 mm diameter, 1.0 pitch).
- Direct replacement: engineered to match the original wheel cylinder's fit, function and performance on the listed applications, then manufactured and tested for quality assurance.
The package contains one wheel cylinder; quantity varies by application, so some of the listed vehicles use two per axle — order accordingly. Country of origin: China.
