The Cusco Brake Master Cylinder Stopper is designed to drastically improve your vehicles braking performance by preventing the Brake Master Cylinder from flexing under heavy load. This results in a stiffer and more responsive brake pedal feel.
During hard braking the toe board where the brake master cylinder is located can twist and this results in decreased brake pedal effort. Brake feel will improve instantly after the Cusco Brake Master Cylinder Stopper is installed as the master cylinder will not flex anymore.
This is a direct bolt-on unit that attaches to the back of the master brake cylinder piston and the suspension tower.
