73-Series Master Cylinder 73-Series master cylinders are designed for applications that require large brake fluid capacity in a leak-proof integral reservoir. Features: Reliable seal/piston design. High pressure die-cast aluminum provides machined-look finish. 1. 1" of stroke provides the fluid displacement needed for a wide variety of applications. Integral 10 oz. reservoir provides plenty of fluid capacity. Internal baffle within reservoir keeps port covered with fluid if reservoir runs low. Engineered bellows from a tight seal and keep elements away from brake fluid. Bellows expands to fully fill reservoir and enables the full volume of fluid to be utilized. Lid designed for easy removal. Features a bail wire produced from high-tensile spring steel (unlike competitor's low-carbon steel), designed to provide consistent clamp force. 1. 8" NPT outlet port, shrouded underneath reservoir to minimize the chance of fitting damage. Front flange mountCylinder weight (varies by bore size): 1. 40 lbsPit Stop USA offers Tilton Integral Reservoir Master Cylinder - .875" Bore 73-875 at low everyday prices.
