Tandem Manual Master Cylinder for C2 Corvettes

Machined from high-pressure die-cast aluminum, the Compact Tandem Master Cylinder weighs just 3.25 lbs.
More than 50% less than the cast-iron factory tandem unit.
Despite the compact size, it has a full 1.10" stroke and the fluid volume needed for high-performance multi-piston calipers
Fluid outputs (1/2"-20 UNF) are provided on both sides of the bore
Plugs and fittings are included to accommodate 3/8"-24, 1/2"-20, and 9/16"-18 IF brake lines
Slotted mount flanges with 3.22" to 3.40" holes bolt right to the factory studs on the Corvette firewall and fit most other domestic cars and trucks from the era

Residual valves for drum brake cars and adjustable proportioning valves to dial in the brake bias are also available.

Two bore sizes provide the correct output for optimal braking performance on all models with Wilwood big brake kits, retrofits to tandem circuit master cylinders for 1963-64 drum brake cars, and a tuning option to provide a softer pedal feel with reduced effort on factory non-power disc brake equipped 1965-67 models.

NOTE: Due to space constraints, the optional proportioning valve mounting kit (P/N 260-14248) will not work with these C2 Corvette tandem master cylinders.
