Dorman engineered this direct-replacement cylinder to match the original's fit, function and performance on the listed vehicles, and it's manufactured and tested for quality assurance. Replacing the wheel cylinder while servicing drum brakes is a quick, reliable way to help maintain proper brake operation. If a leaking or seized wheel cylinder is behind a spongy pedal, fluid at the backing plate, or uneven drum braking, this replaces it. Sold individually as one cylinder; for even braking, service the matching side as directed by the vehicle service procedure. Country of origin: China.
