Abstract
A master cylinder assembly in which the casing defines an annular seal groove defining a forward bore portion forwardly of the annular groove and a rearward bore portion rearwardly of the annular groove. The front end of the piston in the retracted position of the piston is received in the forward bore portion to provide total bearing support for the piston and axial grooves are provided in the forward bore portion to allow recuperative fluid to flow from the associated reservoir and through the axial grooves to the forward bore portion forwardly of the retreating piston.
