EMPI 22mm Buggy Master Cylinder — With Residual Valve & Reservoir (00-6112-0)

EMPI 22mm master cylinder with a built-in residual valve and reservoir. The go-to master cylinder for dune buggies, sand rails, and custom VW-based builds running a single-circuit brake setup. The 22mm bore is large enough to run either a 2-wheel or 4-wheel brake setup, and the residual pressure valve keeps brake pads close to the rotors and reduces pedal travel.
