Description

Feed steady hydraulic pressure to your rear drum brakes with the Dorman - First Stop Drum Brake Wheel Cylinder W37730. Mounted in the rear left upper position, it converts brake-fluid pressure into the outward force that pushes the brake shoes against the drum. It installs as a direct-fit replacement across a wide range of 1984-1998 Ford medium-duty trucks and is built to reproduce the original wheel cylinder's fit, function and performance on the listed applications.

Cast-iron body: a cast-iron housing forms the hydraulic bore.
EPDM rubber cups and boots: durable sealing elements for long service.
Surface-tested bore: the 1.75 in inside-diameter bore is surface-tested to provide an optimum sealing surface for the pressure cups.
Dual inlet threads: two 7/16-24 brake-line inlet ports (7/16 in thread diameter).

Replacing the wheel cylinder while servicing the drum brakes is a cost-effective, straightforward way to help maintain proper brake performance. Signs this part may need replacing include brake fluid weeping at the wheel cylinder, fluid on the drum or shoes, or a soft, spongy pedal. Each package contains one drum brake wheel cylinder; the bleeder screw and bleeder screw cap are not included, so transfer or source them as directed by the service procedure. Diagnose the cause of any hydraulic problem before replacing parts. Country of origin: Italy.
