This direct-replacement cylinder is engineered 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: engineered as a direct match for the original drum brake wheel cylinder on the listed applications.
- Cost-effective service: replacing the cylinder while the drum brakes are already apart is a quick, economical step during a brake job.
- Quality materials: the pressure cups and boots are made with high-quality EPDM rubber.
- Professionally tested: the cylinder bores are surface-tested to give the pressure cups an optimum sealing surface.
A wheel cylinder may need replacing if you see brake fluid seeping at the drum or backing plate, find fluid-soaked shoes, or notice a soft brake pedal. If a leaking or sticking cylinder is the cause, this unit replaces it. Bleed the brakes after installation, following the vehicle service information.

Frequently Asked Questions
Which vehicles does this Dorman wheel cylinder fit?
It fits many vehicles, including the 1995-2000 Ford Contour, 1995-1999 Ford Mystique and 1999-2002 Mercury Cougar. 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. The pistons force the brake shoes against the drum to slow the wheel.
What are signs a wheel cylinder may need replacing?
Common signs include brake fluid leaking at the drum or backing plate, fluid-soaked shoes, a soft or sinking pedal, or a dropping fluid level. Diagnose the cause before replacing parts.
What are the cups and boots made of?
The pressure cups and boots are made with high-quality EPDM rubber. The cylinder bores are surface-tested to give the cups an optimum sealing surface.
Should I replace the wheel cylinder during a drum brake job?
Dorman notes that replacing the cylinder while the drum brakes are being serviced is a cost-effective approach. Bleed the brake system afterward, following the vehicle service information.
