ABSTRACT:
A brake (10) which is adapted to be rotationally coupled with an output shaft includes a housing (11). An inner shaft (33) is adapted to be attached to the output shaft for rotation therewith. A disc assembly (64) includes a plurality of stationary discs (63) carried by the housing (11) and a plurality of rotating discs (62) carried by the inner shaft (33). The rotatable discs (62) are positioned to be engaged by the stationary discs (63). A least one spring (26) biases the stationary discs (63) to engage the rotatable discs (62). A piston (53) is movable to oppose the force of the spring (26). A spacing assembly (80) is positioned on the inner shaft (33) and rotatable therewith. The spacing assembly (80) includes a plurality of o-rings (83) to separate the rotating discs (62) a predetermined axial distance from an adjacent rotating disc (62).
