This rear drum brake wheel cylinder converts hydraulic brake-line pressure into the mechanical force that pushes the brake shoes outward against the drum, with a 0.594 in cylinder bore diameter. Signs it may need replacing include brake fluid seeping at the cylinder, a soft or spongy pedal, or uneven rear braking — if a leaking or seized wheel cylinder is the cause, this replaces it. The listed applications use two wheel cylinders; this listing is sold individually, so order two and replace both sides together for balanced rear braking. Country of origin: China.
Manufacturer part number WC37640.
