Mater Cyl. Compact 7/8in Bare

The Tilton Mater Cyl. Compact 7/8in Bare master cylinder is a precision hydraulic brake component engineered for high-performance vehicles and custom automotive builds where space and weight are critical constraints. Tilton has built a reputation among motorsports enthusiasts and professional mechanics as the gold standard for brake system components, and this compact master cylinder exemplifies that commitment to engineering excellence. This bare unit provides the foundation for custom brake system integration, making it ideal for race cars, hot rods, and street machines requiring bespoke hydraulic configurations.

With a 7/8-inch bore diameter, this master cylinder delivers responsive brake modulation while maintaining a compact footprint that fits tight engine bays and custom-fabricated brake line routing. The bore size strikes an optimal balance between pedal effort and brake line pressure, making it suitable for both street and track applications without excessive pedal travel or harshness. As a bare unit, it arrives without reservoir, proportioning valve, or integrated switches, allowing fabricators complete freedom to specify residual pressure valves, fluid capacity, and brake distribution logic to match their exact vehicle dynamics and weight transfer characteristics.

Professional builders and serious enthusiasts favor this compact master cylinder for custom drum-to-disc brake conversions, independent suspension upgrades, and weight reduction projects where OEM components are too large or heavy. The 3.4 x 2.3 x 8.7-inch dimensions and 0.95-pound weight make it perfect for vehicles where every ounce matters and under-hood real estate is at a premium. Proper installation requires careful line selection, leak testing, and brake fluid bleeding procedures to ensure consistent pedal feel and safety—work best handled by experienced mechanics familiar with custom hydraulic systems.
