Master Cylinder .750in Integral Resevoir

The Tilton Master Cylinder .750in Integral Reservoir (model 73-750) is a purpose-built hydraulic brake component engineered for high-performance racing and custom vehicle applications where precision braking control is non-negotiable. Designed for builders and mechanics upgrading to a dedicated brake system or replacing worn OEM components, this master cylinder combines compact packaging with the reliability demanded in motorsports and street performance builds. The integral reservoir design eliminates external fluid containers, simplifying plumbing and reducing weight—critical advantages in competition vehicles and custom restorations where every pound and inch counts.

At the core of this unit is a 0.75-inch bore diameter matched with a 1.100-inch stroke length, geometry that directly influences brake pedal feel and hydraulic pressure delivery. Constructed from lightweight aluminum in natural finish, the casting resists corrosion while keeping unsprung weight minimal—essential in vehicles where brake response and balance matter. The 2-1/4-inch flange mount accommodates standard firewall or bracket installations, allowing straightforward integration into existing or new brake systems. The internal reservoir architecture manages fluid capacity and thermal stability, ensuring consistent pedal pressure across extended driving sessions or track days where heat buildup can degrade performance in undersized systems.

This master cylinder suits road racers, autocross competitors, street rodders, and restoration specialists who demand modular, repeatable brake architecture. The Tilton 73-series name carries decades of proven performance in motorsports, making it a go-to choice for fabricators building complete brake systems from the ground up. Installation requires basic hydraulic knowledge and compatible wheel cylinders or calipers; ensure all brake lines, fittings, and master cylinder bore sizing are matched to your vehicle's total system volume. Weighing just 1.41 lbs and measuring 8.55 × 2.9 × 8.6 inches, it fits tight engine bays and custom mounting scenarios where space is constrained.
