Abstract: A pressure balanced brake disc stack provides brake discs of greater thickness at the ends and center of the stack and of a lesser thickness at the areas in between the centrally disposed disc and the discs at the end of the stack. The increased thickness of the discs at the end of the stack prevent deflection or distortion of those discs to more evenly distribute the braking pressure applied thereto throughout the stack so as to provide a higher braking coefficient. Additionally, the unique configuration of the brake stack allows for effective heat dissipation at the discs adjacent to the end discs of the stack.
