Serivce brakes work but no air to dash valves
in Air Systems and Brakes
Posted
Im getting a old R model back on the road and the issue Im having right now is no air at the dash valves. The truck airs up good and even holds air overnight. When you press the brake pedal the brakes work as they should, but i cant release the parking brake as the button has no air to it. How are these supposed to be plumbed or could the dash valve be the culprit?
