Dorman - First Stop Drum Brake Wheel Cylinder P/N:W10581
Turn brake-line pressure into the force that pushes your rear brake shoes outward against the drum with the Dorman - First Stop Drum Brake Wheel Cylinder W8266. It installs as a direct-fit replacement in the rear left position on a range of vintage models — including the 1948-1950 Checker A2 and A3, 1950-1952 Checker A4 and A5, 1946-1948 Ford Super Deluxe, and 1946-1948 Mercury Mercury — plus other Checker, Ford (Anglia, Deluxe, Prefect, Taunus) and Mercury applications; see the Buyer's Guide tab for the full list.
As hydraulic fluid enters the cylinder, its pistons move outward through the EPDM cups to press the shoes against the drum. Bore diameter is 1 in or 1.125 in depending on the application. If the original cylinder is leaking, seized, or the cause of a soft, sinking pedal, this replaces it — diagnose the cause before replacing. Sold individually as one rear left cylinder. Country of origin: China.

Brake fluid leaking behind the drum, a soft or sinking pedal, or a seized piston can point to a failed cylinder. Diagnose the cause first, since these signs can have other sources.
