Description

Restore firm, even hydraulic pressure to the rear drum brakes with the Dorman - First Stop Drum Brake Wheel Cylinder W37648. It fits the rear left wheel position and installs as a direct-fit replacement for the listed applications: the 1974-1975 Ford Bronco, 1974 Ford E-100 Econoline, and 1984-1986 Ford Ranger.

A drum brake wheel cylinder is the hydraulic actuator at the wheel — it converts brake fluid pressure sent from the master cylinder into outward piston force that pushes the brake shoes against the drum.

Hydraulic actuation: turns brake fluid pressure into the outward piston travel that applies the shoes against the drum.
Cataloged position: listed for the rear left wheel position on the applications above.
Signs this part may need replacing: brake fluid seeping onto the backing plate, drum, or tire; a soft or spongy pedal; or uneven rear braking. If a failed wheel cylinder is the cause, this replaces it — diagnose the cause before ordering.

How can I tell if my wheel cylinder is failing?

Signs may include brake fluid leaking onto the backing plate, drum, or tire, a soft or spongy pedal, or uneven rear braking. Diagnose the cause before replacing.
