A POWERED VEHICLE INCLUDING A SAHR BRAKE

A powered vehicle includes a spring-applied hydraulic release (SAHR) vehicle brake comprising first and second mutually engageable brake elements. The first brake element is secured to or forms part of a rotatable element of the drive train of the vehicle and the second is non-rotatably moveably mounted on the vehicle such that the first and second elements are mutually engageable with and separable from one another. Mutual engagement of the brake elements causes braking of rotation of the rotatable element.
