Put hydraulic pressure back to work at the rear drums with this Dorman drum brake wheel cylinder, Dorman - First Stop part number W37459. It is a direct-fit rear replacement for the 1979-1984, 1986-1987 and 1989-1995 Toyota Pickup, cataloged for both the rear left and rear right positions. See the Buyer's Guide tab for engine-level details.
When you press the brake pedal, the wheel cylinder turns hydraulic pressure from the master cylinder into force that pushes the brake shoes outward against the drum. Dorman engineered this unit as a direct match for the original wheel cylinder in fit, function and performance, and it is built and tested for quality assurance.
- Ideal replacement: engineered as a direct match for the original drum brake wheel cylinder on the listed vehicles.
- Cost-effective fix: Dorman recommends installing a new cylinder while the drum brakes are apart for service, as a quick and dependable way to help maintain brake performance.
- Quality materials: the cups and boots are made of high-quality EPDM rubber.
- Professionally tested: the cylinder bores are surface-tested to give the pressure cups an optimum sealing surface.
Brake fluid seeping at the backing plate or inside the drum, a soft or sinking pedal, and brakes that pull or grab are signs this part may need replacing. If a leaking or sticking wheel cylinder is the cause, this unit replaces it. Replacing both rear wheel cylinders together is recommended for balanced braking.
