A brake assembly includes a mounting flange having a central opening to receive a shaft, a rotor disc mounted on the shaft and rotatable with the shaft, a float plate having a first friction surface engageable with one face of the rotor disc, and a pressure plate having a second friction surface engageable with another face of the rotor disc. The brake assembly also includes a spring housing, which operates as a piston, and a cylinder coupled to the spring housing to form a fluid pressure chamber. The spring housing moves in a first direction when pressurized fluid enters the fluid pressure chamber and in a second direction when pressurized fluid exits the fluid pressure chamber. The assembly further includes at least one sliding stud to allow axial movement of at least one of the float plate, the pressure plate, and the spring housing to allow axial movement.
