BRAKING SYSTEM

According to the disclosure, a braking system (50) includes a housing (54) configured to rotate around a torque tube (52). A disc stack (58) includes a plurality of stator discs (74) which are coupled to the torque tube (52) and a plurality of rotor discs (78) rotationally coupled to the housing (54). An actuator (82) within the torque tube (52) is configured to compress the disc stack (58). A portion of the torque tube (52) may be configured to insert into an axial assembly (28) of a wheel (10). The housing (54) may be connected to a portion of a wheel rim. The braking system may be present on a wheel (10) instead of or in addition to a main braking system (40) having a main disc stack (42).
