Dorman - First Stop Drum Brake Wheel Cylinder P/N:W49680

Every time you press the pedal, the wheel cylinder turns brake-line hydraulic pressure into the force that pushes your drum-brake shoes outward against the drum — and the Dorman - First Stop Drum Brake Wheel Cylinder W49680 is the rear-left cast-iron cylinder built to do exactly that. It installs in the rear-left position on a range of classic Chevrolet and GMC trucks and vans, including the 1967 Chevrolet C20 Suburban, 1970-1971 and 1973 Chevrolet C20 Pickup, 1972-1973 Chevrolet C20 Suburban, 1972-1973 Chevrolet K20 Pickup and Suburban, 1972 Chevrolet P20 Van, 1973 GMC C25/C2500 Pickup and Suburban, 1972-1973 GMC K25/K2500 Pickup and Suburban, and 1971-1973 GMC P25/P2500 Van (see the Buyer's Guide tab for the full list).

• Direct-fit replacement: engineered to match the original wheel cylinder's fit, function and performance on the listed applications; manufactured and tested for quality assurance.
• Quality materials: made with high-quality EPDM rubber cups and boots for long-lasting performance.
• Professionally tested: the wheel cylinder bores are surface-tested to provide an optimum sealing surface for the pressure cups.
• Ready to bleed: a bleeder screw is included; a bleeder screw cap is not included.

Key specs: 1.125 in inside diameter (bore) and a 7/16-24 brake-line inlet thread, in a cast-iron body. Signs this part may need replacing include brake fluid weeping behind the drum, a soft or spongy pedal, or weak, uneven rear braking; if a leaking or seized wheel cylinder is the cause, this replaces it. Sold individually as one cylinder — for even, balanced braking it's best practice to service the opposite side as a matched pair at the same time. Country of origin: China.
