Notice in the above box we made 2 internal supports for the pivot pin. The stiffness of the pedal box is critical to brake feel. You do NOT want your brake pedal or pedal box flexing! You do not want anything in the brake department flexing as it gives the driver a vague feel of what the brakes are doing. Flex makes modulation of the brakes impossible (or at least very difficult). So, we placed intermediate braces in the box--between the brake and clutch pedal levers--to mitigate any flex that could creep into the system. Also, the front of the foot box is made from 1/2 inch aluminum plate. The top of the foot box is made from 1 inch plate! (All hogged out and lightened up, of course.)
