The Brake System:
Air Brake Quick Release Valve
FIGURE 17. QUICK-RELEASE VALVE.
The air line from the brake valve to the front axle goes to a component known as a quick-release valve. When the brakes are applied, the quick-release valve directs compressed air to the right and left front brake chambers. When the pedal is released, the air from the brake chambers escapes out of the quick-release valve and releases the front brakes. The air in the line from the brake valve escapes through the exhaust valve in the brake valve. |
