Abstract
A brake apply system includes a pressure charging module having a bore carrying a pumping piston that has a base piston surface and an augmentation piston surface. The pressure charging piston separates the bore into an input chamber adjacent the base piston surface and an output chamber adjacent the augmentation piston surface. A suspension damper is hydraulically connected to the input chamber of the pressure charging module, preferably through a continuously open fluid communication circuit. A wheel brake is hydraulically connected to the accumulator output chamber through a selectively open fluid communication circuit. An accumulator is interconnected in the selectively open fluid communication circuit and maintains a pressure charge that is generated by movement of the pumping piston as effected by operation of the damper and that is delivered to the wheel brake through the selectively open fluid communication circuit Through this mechanism the initial pressurization rate of the brake apply system is increased.
