Master Cylinder 13/16in

The Master Cylinder 13/16in (TILTON 78-812) is a precision hydraulic brake component engineered for high-performance racing and motorsport applications. Designed for use with Tilton 900-Series pedal assemblies, this master cylinder delivers the responsive pedal feel and consistent braking modulation required in competitive driving environments. Whether you're building a track-focused street car, vintage race vehicle, or professional motorsport setup, this compact aluminum unit provides the hydraulic foundation for safe, predictable brake system performance.

This master cylinder features a 0.813-inch bore diameter with a 1.100-inch stroke, engineered to balance brake line pressure and pedal travel for optimal modulation and feel. Constructed from lightweight aluminum in natural finish, the 78-Series design supports both direct and remote reservoir mounting configurations, allowing flexibility in system layout and packaging constraints. The 13/16-inch bore size is ideal for vehicles requiring moderate hydraulic volume and pressure characteristics, making it well-suited for mid-weight racing platforms and street applications seeking refined brake control without excessive pedal effort.

Driver-focused builders and racing teams benefit from this master cylinder's proven Tilton engineering and direct compatibility with 900-Series pedal assemblies, ensuring matched performance across the entire brake system. Installation requires proper brake line routing and bleeding procedures to eliminate air and establish full hydraulic pressure. The unit's compact footprint (3.4 x 2.3 x 8.7 inches) and lightweight aluminum construction (0.65 lbs) make it ideal for space-constrained engine bays and weight-conscious builds. For optimal results, pair with quality brake fluid and compatible calipers matched to your vehicle's weight and intended braking demands.
