Jass Performance Brake Master Cylinder Stopper (Miata/MX5 NA/NB)
This brake stopper is a rigid structural component designed to mechanically counteract deflection in the brake booster and firewall mounting during high-force application. By maintaining the fixed position of the master cylinder, the unit ensures maximum transfer of pedal input to hydraulic pressure. This results in a significant improvement in pedal firmness and responsiveness.
