When a leaking or seized wheel cylinder leaves your drum brakes soft or dragging, the Dorman - First Stop Drum Brake Wheel Cylinder W28720 puts the hydraulics back to work: it uses brake-line pressure to push its internal pistons outward and force the brake shoes against the drum. Engineered as a direct replacement for the original wheel cylinder on the listed vehicles, it drops into the front-left and front-right positions on classic Dodge trucks and vans, including the 1957-1958 D200 Pickup, 1959 D100 Pickup, 1960 D100 Series, 1960 / 1961-1964 / 1966-1968 P300 Van, and 1961-1964 P200 Van (engine: All).
Cast-iron body: cast-iron cylinder construction.
EPDM rubber cups and boots: sealing cups and dust boots made from EPDM rubber.

Bleeder screw included: comes with a bleeder screw; a bleeder screw cap is not included.
