Brake chambers are used on truck and trailer air brake systems, located at each wheel, where compressed air is converted into a mechanical force used to apply the brakes and stop the vehicle. They are also designed to apply the the brakes automatically in the event that there is a loss of system air pressure. This happens because the air pressure holding back the heavy parking/emergency spring dissipates allowing the spring to extend the pushrod which in turn applies the brake. There are designs to cover Cam Brake and also Disc Brake applications, along with different sizes and strokes. The most common strokes are standard and long stroke.

The load sensing valve (L.S.V.) serves the purpose of automatically adapting the brake pressure and therefore the brake force according to the load of the vehicle.

The governor valve, which is usually compressor mounted, operates in conjunction with the compressor and maintains reservoir air pressure between a predetermined maximum and minimum pressure. The unloader valve allows the air compressor to operate in an unloaded state, where the compressor piston continues to reciprocate, but does not build additional air pressure in the vehicles compressed air system.

The purpose of the limiting valve is to reduce the air pressure supplied to the front brakes during moderate brake applications. Because there is usually more loads on the rear wheels of a truck compared to the front wheels, the front wheels have more tendency to lock up during a brake application, the limiting valve reduces this tendency These valves are also used to reduce the supply pressure to other auxiliary Equipment.

Air Suspension Control Valves are used to automatically control the vehicle’s ride height by inflating and deflating the air suspension bellows to adjust for variations between loaded and unloaded vehicles. They are also used for cab suspensions to provide ride comfort for the operator and for bus suspension application, including kneeling capability.

The Gearbox Valve has several functions & purposes & the valve body consists of a number of valves. The valves are referred to by the shifts they are responsible for. For example, the third-fourth valve determines an upshift from third gear to fourth gear & the fourth-third is responsible for a downshift from fourth gear to third. Each valve is connected to a shifter in the vehicle. The manual valve is the one controlled by the driver.

On some trucks & trailers, the distance from the brake chambers to the foot valve is too far to cause immediate application of the brake when the foot valve is depressed. This is called brake lag. To correct this situation, a relay valve is installed near the rear brake chambers. A large diameter pipe is connected between the service reservoir and relay valve. The air line from the foot valve to the relay valve now becomes a control line that signals to the relay valve the amount of air to be drawn from the service reservoir for faster application of the brakes.
