Dorman - First Stop Drum Brake Wheel Cylinder P/N:W134494
Put fresh hydraulic force behind your rear brake shoes with this Dorman drum brake wheel cylinder, part number W37668 from the First Stop line, a direct-fit replacement for the 1986-1992 Ford Taurus and 1986-1992 Mercury Sable. Engine details are listed in the Buyer's Guide tab.
Inside the rear drum, the wheel cylinder converts brake-pedal hydraulic pressure into motion. Its pistons push outward to press the brake shoes against the drum. Dorman engineered this unit to match the fit, function and performance of the original wheel cylinder on these vehicles. Each cylinder is manufactured and tested for quality assurance.
A wheel cylinder may need replacing if you see brake fluid seeping inside the drum, wet or contaminated shoes, a soft or sinking pedal, or brakes that grab. Diagnose the cause before you order. If a leaking cylinder is the problem, W37668 replaces it.

What are signs a wheel cylinder may need replacing?
Brake fluid leaking inside the drum, wet or contaminated shoes, a soft or sinking pedal, or grabbing brakes may be signs of a failing cylinder. Diagnose the cause before replacing it.
Should I replace the wheel cylinder during a drum brake job?
Dorman calls replacing the cylinder during drum brake service a cost-effective fix. Replacing both sides together is commonly recommended, and the brakes should be bled per the service information.
