A brake ( 10 ) for the drive shaft of a vehicle or machine includes a housing ( 11 ) having an open end ( 12 ) which is adapted to be attached to the vehicle. A shaft is received in the housing ( 11 ) and is adapted to be attached to the vehicle drive shaft for rotation therewith. The shaft has a splined outer surface. A disc assembly ( 30 ) includes a plurality of rotatable discs ( 29 ) carried by the splined surface of the shaft, a plurality of stationary discs ( 32 ) which alternate with the rotatable discs ( 29 ) and a primary stationary disc ( 33 ) located at the end of the disc assembly ( 30 ), proximate to the open end ( 12 ) of housing ( 11 ). As mounted, a plurality of springs ( 42 ) cause the stationary discs ( 32 ) to engage the rotatable discs ( 29 ) to apply a braking torque to the shaft. A piston ( 21 ) is moveable to oppose the spring force and allow free rotation of the rotating discs ( 29 ). Prior to mounting, a plurality of shipping bolts ( 25 ) hold the disc assembly ( 30 ) together and axially aligned. Prior to mounting, springs ( 42 ) are held in place by a spring retaining ring ( 40 ) and by pin assemblies ( 44 ).
