Years of development have went into this all new TBM Billet Modular Master Cylinder which answers the needs of racers and hot rodders alike. For years our brakes have rapidly developed to create world class braking systems. However, the control system of a car's braking system is the master cylinder. While most brake master cylinders are cast spinoffs of old technology that lack options in internal and physical outside sizing, have leaking issues, and reliability issues. The TBM brake master is a ground up engineered design to remedy those questions and offer new solutions for builders.
