Dorman - First Stop Drum Brake Wheel Cylinder P/N:W610189
Turn pedal pressure into shoe-to-drum braking force with the Dorman drum brake wheel cylinder, part number W13387 from the Dorman First Stop line. It fits many vehicles, among them the 1958-1964 Chevrolet Impala, 1969-1973 Chevrolet Blazer and 1964-1973 Chevrolet C10 Pickup. See the Buyer's Guide tab for the full list and engine details.
When you press the brake pedal, hydraulic pressure from the master cylinder pushes the wheel cylinder's pistons outward and presses the brake shoes against the drum. The catalog lists this unit for the front left, rear left and rear right positions. Dorman engineered this direct-replacement wheel cylinder to duplicate the original unit's fit, function and performance, and it is manufactured and tested for quality assurance.
Signs that a wheel cylinder may need replacing include fluid seeping at the drum or backing plate, a soft or spongy brake pedal and a dropping brake fluid level. Diagnose the cause before replacing parts, and bleed the brake system after installation.
