A wheel cylinder uses brake-line hydraulic pressure to push its pistons outward, forcing the brake shoes against the drum. It is manufactured and tested for quality assurance.

• Cast iron with EPDM cups and boots: a cast iron body paired with high-quality EPDM rubber cups and boots.
• Surface-tested bore: the cylinder bore is surface-tested for an optimum sealing surface for the pressure cups.
