A wheel assembly for an electrical vehicle. The wheel assembly comprising a hub integral with an electrical motor, and a fluid actuated fail-safe brake fitted to the assembly with at least one braking surface for frictional engagement with the rotor of the electrical motor. The brake in its non-actuated state is engaged with the rotor, and when fluidally actuated the brake is released to allow rotation of the rotor. A solenoid valve having a normally open state is in fluid communication with the pressurised fluid used to fluidally actuate the brake, and the solenoid valve is closed when electrically powered thereby allowing fluid actuation to release the brake. In the event of a loss of electrical power the solenoid valve will revert to the normally open state, so that the brake is non-actuated and applies a braking force to the rotor.
