This drum brake wheel cylinder converts hydraulic line pressure into the outward force that pushes the brake shoes against the drum. It carries two opposed pistons in a 0.938 in bore, bolts on through two mounting holes, and uses an inverted flare port. A bleeder screw is included, and every unit is 100% pressure tested for leak free service so it installs with no modification to the original hardware.
