Abstract: A brake (10) for a wheel of a vehicle includes a housing (11) having one end closed by an end plate (12) which is adapted to be attached to the vehicle. An axle assembly (26) is received in the housing (11) and is adapted to be attached to the wheel for rotation therewith. The axle assembly includes a drive surface (33) which carries a shaft sleeve (48) having a splined outer surface (52). A disc brake assembly (55) is immersed in a fluid in the housing (11) and includes a plurality of rotatable discs (54) carried by the splined surface (52) and a plurality of stationary discs (56) which alternate with the rotatable discs (54) to form the disc brake assembly (55). Each of the stationary discs (56) has ears (58A, 58B) which are received in brackets (59) carried by the housing (11). A piston ring (62) is moveable to cause the stationary discs (56) to engage the rotatable discs (54) to apply a braking torque to the wheel.
