摘要： A spring applied, hydraulically released brake includes a housing having an open end adapted to align with a vehicle surface and an internal ring extending from an inner perimeter of the housing; a piston; a disc stack including a thicker stationary disc including a tab with a hole therethrough, the hole receiving a slotted spring pin, the slotted spring pin slidably receiving a pin spring over a portion thereof; and a spring assembly adapted to urge the piston into contact with the thicker stationary disc to establish a default position of the brake; where, in a released position of the brake, the piston is not in contact with the thicker stationary disc, and the pin spring urges the thicker stationary disc into contact with the internal ring of the housing to thereby prevent the thicker stationary disc from free floating.
