Dorman - First Stop Drum Brake Wheel Cylinder P/N:W4801
Keep your rear drum brakes applying steady, even pressure with the Dorman - First Stop Drum Brake Wheel Cylinder (W37864). Mounted at the rear, it converts hydraulic pressure from the brake line into the outward force that pushes the brake shoes against the drum. It drops in as a direct-fit replacement for the 1990-1993 Chrysler Imperial, 1990-1995 Chrysler LeBaron, 1990-1994 Chrysler New Yorker, 1990-1995 Chrysler Spirit, 1990-1993 Dodge Dynasty, 1990-1995 Dodge Spirit, and 1990-1995 Plymouth Acclaim (all engines).
Engineered to match the original wheel cylinder's fit, function, and performance on the listed vehicles, and manufactured and tested for quality assurance. Replacing the wheel cylinder while servicing the drum brakes is a fast, sure way to help maintain proper brake performance. Sold individually; each listed application uses two (one per rear wheel), so order two and replace both sides together for balanced braking. Country of origin: China.
