19 . In a vehicle with dual parking control valves, once air pressure is lost and the spring brakes come on:

In a vehicle with dual parking control valves, there is a separate air tank that can be used to temporarily release the spring brakes if they have been activated due to low air pressure. Pushing in the proper control will release the spring brakes for a short period of time, allowing the driver to move the vehicle in an emergency.

20 . In cold weather, an alcohol evaporator should be checked and filled:

Once a month. An alcohol evaporator can help prevent ice from building up in an air brake system. In cold weather, the evaporator should be checked and refilled every day.

21 . Braking mechanisms are located ____ a brake drum.

On top of Drum brakes are attached to the wheels and located on the axles of a vehicle. The braking mechanisms that cause the vehicle to stop can be found inside of a drum brake.

22 . Front brake limiting valves were intended to:

Remove uncertainty when applying the brakes. Some older vehicles with air brakes have front brake limiting valves. These valves were intended to reduce the risk of front wheels skidding. However, research has shown that such devices are unnecessary, so they should be left in the "normal" position.

23 . When operating a vehicle with a dual brake system, a driver should:

Pump the pedal about 20 times to build pressure, then begin driving. Before driving a vehicle with a dual air system, allow time for the air compressor to build up a minimum pressure of 100 psi in both the primary and secondary systems.

24 . How is the parking brake released?

By tapping the accelerator twice In vehicles with air brakes, the parking brake is controlled by a knob. The knob is pulled out to apply the brakes, and pushed in to release them.

25 . A one-way check valve:

Holds the spring brakes in position until they are used. A one-way check valve is required to be between an air compressor and the first main reservoir. This valve prevents air from escaping the system if the air compressor develops a leak.
