Abstract: 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.

Abstract: A hydraulic caliper assembly includes a caliper brake housing including two opposing pairs of two piston assemblies, each of the pairs of two piston assemblies adapted to place a respective stator assembly of a pair of stator assemblies in a braking position, where the caliper brake housing is a unitary, cast component having an internal fluid porting system fluidly coupling each of the piston assemblies with a source of hydraulic fluid, and where each of the piston assemblies have a common configuration.

Abstract: A stator pad assembly includes a backing plate including a plate slot extending to a plate slot end, the backing plate carrying a stator lining including a lining slot extending to a lining slot end, the lining slot being generally positioned with a portion of the plate slot such that the plate slot end and the lining slot end are of similar position, and the plate slot defining a tool-engaging surface adapted to receive a tool to thereby cause the stator pad assembly to travel.

Abstract: A brake (10) includes a housing (12) formed from a first housing portion (14) capable of receiving a second housing portion (16). The first housing portion (14) houses a piston (18) and a plurality of springs (20), and the second housing portion (16) houses an alternating arrangement of discs (52) for enacting a braking function. The second housing portion (16) further includes torque pin holes (80) for receiving torque pins (82) therein. Each torque pin (82) is secured with a plug (84) to secure stationary discs (54A, 54B, 54C) in place. The stationary discs (54A, 54B, 54C) have extending ears (74) positioned between torque pin grooves (76), which further receive the torque pins (82).
