Replace a worn or leaking rear wheel cylinder with this Dorman drum brake wheel cylinder, part number W37983 from the Dorman - First Stop line, which turns brake-fluid pressure into the force that pushes the brake shoes out against the drum. It fits many vehicles, among them the 1998-2008 Subaru Forester, 2003-2004 Subaru Outback and 1995-1999 Subaru Legacy. See the Buyer's Guide tab for the full list.
Dorman engineered this direct replacement to match the original wheel cylinder in fit, function and performance on the listed applications. Each unit is manufactured and tested for quality assurance.
- Ideal replacement: specifically engineered as a direct match for the original drum brake wheel cylinder on the listed applications.
- Cost-effective fix: replacing the cylinder while the drum brakes are already apart for service helps maintain brake performance.
- Quality materials: built with high-quality EPDM rubber cups and boots.
- Professionally tested: the wheel cylinder bores are surface-tested to provide an optimum sealing surface for the pressure cups.
Signs a wheel cylinder may need replacing include brake fluid seeping inside the drum or onto the backing plate, a soft or sinking pedal, and brakes that pull or grab. Inspect the brake system to confirm the cause before replacing parts, and bleed the brakes after installation.
