Replacing the cylinder while servicing the drum brakes is a fast, straightforward way to help maintain proper brake operation.

Some listed applications use one cylinder per axle while others use two; the package contains one cylinder. Country of origin: China.
It's the hydraulic actuator in a drum brake. Brake-fluid pressure enters the cylinder and drives its cups and pistons outward, forcing the brake shoes against the drum to slow the wheel.
How many do I need for my vehicle?
It's sold individually and this listing is for one cylinder. Some listed applications use one per axle while others use two, so check the Buyer's Guide tab for your vehicle's quantity.
Is a bleeder screw included?
No. Per the catalog, the bleeder screw and bleeder screw cap are not included. Consult the vehicle service information for the correct fasteners and parts.
What is it made of and what are the key specs?
It has a cast iron body with a 1.375 in inside diameter, a 7/16-24 inlet thread (7/16 thread diameter), and EPDM rubber cups and boots. Country of origin: China.
What are signs this cylinder may need replacing?
Signs may include brake fluid seeping at the wheel or backing plate, a soft or low pedal, and weak or uneven braking at that wheel. Diagnose the cause before replacing.
