A powered vehicle (10) includes a power source for generating energy to power the vehicle; a spring-applied hydraulic release (SAHR) vehicle brake (11) comprising first (12) and second (13) mutually engageable brake elements. The first brake element (12) is secured to or forms part of a rotatable element of the drive train of the vehicle (10) and the second (13) is non-rotatably moveably mounted on the vehicle such that the first and second elements (12,13) are mutually engageable with and separable from one another. Mutual engagement of the brake elements (12,13) causes braking of rotation of the rotatable element, and the SAHR vehicle brake (11) includes (i) a resiliently deformable member (19) acting on the second brake element (13) so as to urge the first and second brake elements (12,13) into mutual engagement and (ii) a non-electric control circuit for applying pressure to the second brake element (13) so as to oppose the action of the resiliently deformable member (19) and thereby normally maintain the first and second brake elements separated from one another. The vehicle (10) includes an energy convertor (28) for generating energy in the control circuit in proportion to the speed of the vehicle and/or the energy generated by the power source, the energy convertor (28) energising the control circuit while the speed of the vehicle and/or the energy generated by the power source exceeds a threshold and de energising the control circuit to permit mutual engagement of the first (12) and second (13) elements under the influence of the resiliently deformable (19) member when the speed of the vehicle and/or the energy generated by the power source is less than the threshold.
