Push the rear brake shoes against the drum with dependable hydraulic force using the Dorman First Stop Drum Brake Wheel Cylinder W37692. It installs as a direct-fit rear wheel cylinder for the 1983-1986 Nissan 720 [All] and 1986-1989 Nissan D21 [All], and Dorman engineered it to match the original cylinder's fit, function and performance on those applications. When a leaking or seized cylinder is behind spongy, uneven, or dragging drum braking, replacing it while you service the drums is a fast, cost-effective way to keep the hydraulic side working as intended.
