Turn hydraulic brake-line pressure into the force that pushes the shoes outward against the drum with the Dorman - First Stop Drum Brake Wheel Cylinder W37578. It installs as the rear left wheel cylinder and drops in as a direct-fit replacement for the 1972-1980 Toyota Land Cruiser (All engines), engineered to match the fit, function and performance of the original cylinder on the listed applications, then manufactured and tested for quality assurance.
- Cast-iron body: bores are 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.
- 0.875 in bore: with an M10 x 1.0 (10 mm) inlet thread.
- Bleeder screw included: the bleeder screw cap is not included.
Replacing the wheel cylinder while servicing the drum brakes is a fast, sure way to help maintain proper brake performance. A weeping or seized cylinder can cause a low or sinking pedal, uneven braking, or fluid on the backing plate — if the cylinder is the cause, this replaces it. Sold individually as one rear left cylinder; replacing both sides together is good practice for balanced braking. Country of origin: Taiwan.
