The master cylinder is the heart of your brake hydraulics, converting pedal force into hydraulic pressure. Our master cylinders and proportioning valves collection ensures that force is delivered smoothly, consistently, and in the right balance.

Upgraded master cylinders are available in different bore sizes to match aftermarket callipers and brake kits. Choosing the right size ensures the perfect pedal feel too small and the pedal will be long and soft, too large and it becomes overly stiff. Precision-engineered units provide consistent pressure and long-term reliability.

Proportioning valves are equally critical, especially on vehicles with brake upgrades. Adjustable valves let you fine-tune the front-to-rear brake bias, preventing premature lockup and ensuring balanced stopping performance. This is particularly important on high-horsepower cars, where weight transfer under braking can be extreme.

Together, master cylinders and proportioning valves allow you to get the most out of your brake system upgrades. They provide the fine control needed to match components, balance performance, and ensure your braking feels natural and confidence-inspiring.

Our master cylinders and proportioning valves collection gives you the control you need to tailor your braking system to your exact requirements, whether for road use, track days, or full competition builds.
