The AP Racing Ø 22.2 mm trunnion-mounted master cylinder, part number CP7854-94PRTE, is a push-type model designed for single-circuit competition hydraulic systems. Its one-piece piston and pushrod assembly and its extra-short stroke before the fluid supply is cut off contribute to the systemâ€™s efficiency.

The hard-anodized aluminum alloy body is equipped with a bellows for protection. The pivot operates on needle bearings.
