A brake adapted to be rotationally coupled with a shaft and in communication with a fluid source and a negative pressure source, the brake including a housing defining a chamber therein. A disc assembly is positioned within the chamber and includes a plurality of stationary discs carried by the housing and a plurality of rotating discs carried by the shaft. The rotatable discs and stationary discs are positioned for engagement. A piston is movable to cause the stationary discs to engage the rotatable discs. A first fluid input is in communication with the fluid source, providing a constant supply of fluid to the chamber. A second fluid input is in communication with the fluid source, providing fluid when the stationary and rotating discs are caused to engage.
