Dorman builds it as a direct replacement to drop in like the original wheel cylinder on the listed applications, with each unit manufactured and tested for quality assurance. Replacing the cylinder while you service the drum brakes is a fast, straightforward way to renew the hydraulic side of the system. If a leaking or seized wheel cylinder is the cause of fluid at the backing plate or a sinking pedal, this replaces it. Country of origin: China.
