Construction & Design

The master cylinder features a robust flange mount body crafted to withstand the rigors of high-performance braking systems. The aluminum reservoir is precision-machined from billet aluminum, providing a lightweight yet durable container for brake fluid. Its finned design not only pays homage to traditional hot rod aesthetics but also aids in dissipating heat, helping to maintain optimal fluid temperature during extended use.

The compact length of the unit is achieved through careful engineering, allowing it to fit into confined spaces without sacrificing hydraulic efficiency. The flange mount configuration offers secure attachment points and simplifies installation in custom or modified vehicles where space constraints are common.

Installation & Fitment

This master cylinder is designed for remote flange mounting, providing flexibility in placement relative to the pedal assembly. It can be installed in a variety of configurations depending on vehicle layout and builder preference. The compact size makes it especially suitable for applications where space is limited, such as engine swaps, hot rods, and race cars.

No special modifications such as cutting or drilling are required for installation when used with compatible mounting brackets and hardware. The unit integrates seamlessly with existing hydraulic brake lines and components, though proper brake line routing and bleeding are essential for optimal performance.
