Master Cyl. Compact Bare 13/16in

The Master Cyl. Compact Bare 13/16in from TILTON is a precision hydraulic brake master cylinder engineered for high-performance and racing applications where space is at a premium and brake response must be immediate and consistent. This compact design suits builders of custom hot rods, track-focused street cars, and motorsports platforms where traditional full-size master cylinders create clearance conflicts or add unnecessary weight. The 13/16-inch bore size strikes a critical balance between brake line pressure development and pedal effort, making it ideal for vehicles running upgraded brake systems or multiple circuit configurations.

Built from aluminum and finished in black anodized coating, the Master Cyl. Compact Bare 13/16in delivers durability while resisting corrosion in engine bay environments. The 0.813-inch bore diameter with a 1.100-inch stroke creates efficient fluid displacement, generating the pressure curve needed for responsive brake modulation without excessive pedal travel. The 2-1/4-inch flange mount pattern accepts standard brake line ports, allowing seamless integration into existing hydraulic layouts or new custom installations. At just 0.82 lbs, the bare aluminum construction minimizes unsprung weight while the compact footprint—6 x 2 x 9 inches—fits tight engine compartments where every inch matters.

Mechanics and fabricators restoring classic muscle cars, building tube-chassis racers, or upgrading aging brake systems will appreciate TILTON's reputation for precision hydraulic components. The bare cylinder design allows builders to select their own residual pressure valves, proportioning blocks, and integrated components based on specific brake architecture and master cylinder compatibility requirements. Installation requires careful line sizing and pressure balancing—verify bore diameter against your brake circuit design and confirm the 2-1/4-inch flange mates your mounting surface before assembly.
