5/8in Master Cylinder

The TILTON 5/8in Master Cylinder (Model 76-625) is a compact, precision-engineered hydraulic brake component designed for high-performance street and race vehicles where weight savings and compact packaging are critical. Built for drivers and mechanics who demand reliable brake modulation in confined engine bays, this master cylinder delivers the responsiveness required for track-focused builds, vintage restorations, or modern performance platforms that benefit from optimized brake architecture. Its 0.625-inch bore and 1.100-inch stroke provide a balanced pedal ratio suitable for both manual and power-assisted brake systems.

Constructed from black anodized aluminum, the 5/8in Master Cylinder combines durability with weight reduction—essential for vehicles where every tenth of a pound matters. The aluminum construction resists corrosion while the anodized finish provides a protective barrier against hydraulic fluid exposure and environmental degradation. This master cylinder features a direct/remote reservoir design, allowing flexible mounting configurations to suit custom brake line routing and engine bay layouts. The 2-1/4-inch flange mount integrates seamlessly into standard brake system interfaces, while its compact 3.45 x 2.45 x 8.8-inch footprint minimizes obstruction in tight installations. At 0.85 lbs, the lightweight design contributes meaningfully to unsprung and overall vehicle weight reduction.

Mechanics and enthusiasts favor TILTON master cylinders for road-course racing, autocross competition, and street performance builds where brake feel and system reliability are non-negotiable. The 76-series architecture supports both front-mounted and remote reservoir configurations, making it adaptable to custom chassis layouts, tube-frame vehicles, and mid-engine applications. Proper installation requires attention to reservoir height, fluid level, and bleed procedures to eliminate air and ensure consistent brake pedal response. This master cylinder is engineered to work with DOT 3, DOT 4, or DOT 5.1 brake fluid and integrates with proportioning valves and bias adjuster systems commonly found in performance brake setups.
