Function and Operation:
Parking Brake Control:
The handbrake valve, often a push/pull type with a distinctive knob (e.g., yellow, four-sided), is typically dashboard-mounted and provides in-cab control of the parking brakes.
Air Supply and Release:
Pushing the valve supplies compressed air to release the spring brakes, while pulling it exhausts the air, applying the spring brakes to secure the vehicle.
Safety Feature:
Some variants include an emergency release device to prevent automatic braking if the parking brake circuit is defective. The valve can also be pressure-sensitive, automatically moving to the applied position if system pressure drops below a certain level (e.g., 20-30 psi).
Trailer Control:
In systems with trailers, the handbrake valve can also actuate the trailer control valve, affecting the trailer’s braking system.
