The disclosure relates to a brake release system for a vehicle comprising a parking brake having a brake chamber. The brake release system comprises a regular air supply passage, and an auxiliary air supply passage configured to supply pressurized air to the brake chamber for releasing the parking brake in case of failure of the regular air supply passage. A valve device is provided in the auxiliary air supply passage, the valve device comprising an exhaust port. A pressure-responsive element is configured to actuate the valve device and configured to be in fluid communication with the regular air supply passage, such that when pressurized air is supplied through the regular air supply passage then the pressurized air activates the pressure-responsive element so as to actuate the valve device to move to a closed first state, and when no pressurized air is supplied through the regular air supply passage then the pressure-responsive element is deactivated to allow the valve device to move to an open second state.
