Dorman - First Stop Drum Brake Wheel Cylinder P/N:W10581
Send firm hydraulic pressure to your drum brake shoes with the Dorman First Stop Drum Brake Wheel Cylinder (P/N W10580). Cataloged as a front left upper unit, it drops in as a direct-fit replacement for classic Mopar drum-brake systems — including the 1949-1955 Dodge Coronet, 1949-1951 Plymouth Deluxe, 1949-1950 Plymouth Special Deluxe, 1949-1954 Plymouth Suburban, 1951-1953 Plymouth Cambridge, 1951-1952 Plymouth Concord, 1951-1953 Plymouth Cranbrook, 1953-1954 Plymouth Belvedere, 1953-1954 Plymouth Savoy, 1954-1955 Dodge C-1, 1954-1956 Dodge C-3, 1954 Plymouth Plaza, and 1956 Dodge C-4 (see the Buyer's Guide tab for the full list). It is built to replace the fit, function, and performance of the original wheel cylinder on the listed vehicles.
Mounted in the drum brake assembly, the wheel cylinder takes fluid pressure from the master cylinder and pushes its internal pistons outward to force the brake shoes against the drum. If a leaking or seized wheel cylinder is the cause of a soft pedal, fluid weeping at the wheel, or uneven drum braking, this replaces it.
Sold individually; this listing is for one wheel cylinder. Country of origin: China.
