Get hydraulic force back to the rear left drum with the Dorman drum brake wheel cylinder W37581 from the First Stop line. When you press the pedal, it pushes the brake shoes out against the drum. It fits many vehicles, among them the 1988-1989 Honda Accord, 1980-1989 Honda Civic and 1988-1989 Honda CRX, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full vehicle list and engine details.
- Ideal replacement: Dorman engineered it to match the original wheel cylinder's fit, function and performance on the listed vehicles, and it is manufactured and tested for quality assurance.
- Cost-effective fix: Replacing the wheel cylinder during a drum brake service is a practical way to help keep the hydraulic side of the rear brakes in good working order.
- Quality materials: Built with high-quality EPDM rubber cups and boots.
- Professionally tested: The cylinder bores are surface-tested for an optimum sealing surface for the pressure cups.
Signs a wheel cylinder may need replacing include brake fluid seeping around the drum or backing plate, fluid-soaked brake shoes, or a soft or sinking pedal. Diagnose the cause first. If a leaking or sticking wheel cylinder is the problem, W37581 replaces it at the rear left position.

Frequently Asked Questions
Will this work as a 1980-1989 Honda Civic brake wheel cylinder replacement?
Yes. It is listed for the 1980-1989 Honda Civic at the rear left position. Check the "Vehicles it fits" section to confirm your exact vehicle.
What does a drum brake wheel cylinder do?
When you press the brake pedal, hydraulic pressure pushes the wheel cylinder's pistons outward. This forces the brake shoes against the drum to slow the wheel.
What are the cups and boots made of?
Dorman uses high-quality EPDM rubber cups and boots on this wheel cylinder. The bores are surface-tested to give the pressure cups an optimum sealing surface.
What are signs a wheel cylinder may need replacing?
Look for brake fluid around the drum or backing plate, fluid-soaked shoes, or a soft or sinking pedal. Diagnose the cause before replacing parts.
Do the brakes need bleeding after installation?
Yes. Replacing a wheel cylinder opens the hydraulic system, so the brakes must be bled afterward. Follow the vehicle service information for installation and bleeding.
