Raybestos WC37856 Drum Brake Wheel Cylinder rear, part of the Element3 line, is a direct‑replacement wheel cylinder for rear drum brake systems. This OE‑quality component is designed to fit the rear drum brake assemblies on 1991–1994 Ford Explorer models and is also listed as compatible with the 1992 Mazda Navajo, replacing the OEM part 2037856. The WC37856 uses hydraulic pressure to actuate the brake shoes against the inside of the drum, restoring proper rear braking function when servicing drum‑brake systems.
