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. The SAHR vehicle brake includes (i) a resiliently deformable member acting on the second brake element so as to urge the first and second brake elements into mutual engagement and (ii) a hydraulic control circuit for applying hydraulic pressure to the second brake element so as to oppose the action of the resiliently deformable member and thereby normally maintain the first and second brake elements separated from one another.
