Dorman - First Stop Drum Brake Wheel Cylinder Kit P/N:3577
Service a worn rear drum brake wheel cylinder with the Dorman First Stop Drum Brake Wheel Cylinder Repair Kit, part number 46347, which supplies components designed to match the original parts required for the repair.

The wheel cylinder turns hydraulic pressure from the master cylinder into the force that pushes the brake shoes outward against the drum. As its internal components wear, brake fluid can seep out and braking may suffer. This kit is intended to replace those worn components at the rear drum brakes of the listed applications.
