A brake system that uses a quick release valve in place of a double check valve to optimize the timing of the release of pressurized air from the brake chambers and supply lines is provided. The quick-release valve further includes a threaded exhaust port that functions as a second supply port. By using the threaded exhaust port as a second supply port, the diaphragm in the quick release valve acts similar to an unbiased diaphragm double check valve during periods of increasing air pressure, but retains the functionality of a quick release valve during periods of decreasing air pressure by favoring release through the threaded exhaust port.
