Master Cylinder .875in Integral Reservoir

The Master Cylinder .875in Integral Reservoir from TILTON is a precision hydraulic component designed for high-performance braking systems in racing, motorsports, and specialized automotive applications. This integral reservoir master cylinder combines the brake fluid storage and pressure-generating functions into a single compact unit, eliminating the need for a separate external reservoir and reducing overall system complexity. Built for vehicles that demand reliable, responsive brake modulation under extreme conditions, this cylinder serves drivers and teams who prioritize consistent pedal feel and thermal stability during sustained high-speed operation.

The 73-Series Master Cylinder features a 0.875-inch bore diameter and 1.100-inch stroke, engineered to deliver the displacement and force characteristics required for balanced brake bias in competition vehicles. The integral reservoir design maintains optimal fluid level and minimizes air entrapment, critical factors in systems where brake fade and sponginess are unacceptable. Constructed from aluminum, the cylinder offers lightweight construction without sacrificing durability, while the natural finish provides corrosion resistance suitable for demanding environments. The 2-1/4-inch flange mount interface ensures straightforward installation on compatible brake master cylinder brackets, and the compact dimensions (8.7 x 2.5 x 10 inches) allow flexible routing in tight engine bays common to race cars and performance builds.

This master cylinder is ideal for road racing, autocross, drag racing, and street performance enthusiasts building custom hydraulic brake systems from the ground up. Its integral reservoir configuration is particularly valued in vehicles with space constraints or where system simplicity enhances reliability. Installation requires compatibility with hydraulic brake line sizes and vehicle-specific master cylinder bracket geometry; consultation with brake system engineers or suspension specialists is recommended to ensure correct bore selection and proper brake bias tuning for your specific vehicle weight distribution and brake line layout. The lightweight aluminum construction makes it especially attractive for weight-sensitive competition platforms.
