Abstract:
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.

Claim (Index 25):
The vehicle of  claim 24 , wherein when the detected speed is less than a threshold value or is zero and the hydraulic release valve and the proportional hydraulic valve are actuated such that pressurised fluid is applied to the second brake element whereby separation of the first and second brake elements from one another occurs, progressive de-activation of the proportional hydraulic valve controlledly vents pressure acting on the second brake element via (i) the hydraulic release valve in its pressure relief configuration, (ii) the proportional hydraulic valve and (iii) the drain or tank connected thereto whereby progressively to cause mutual engagement of the first and second brake elements.
