Question 80
All vehicles with air brakes must have a low air pressure warning signal. True or False?


Answer 80

Question 81

Answer 81
When the air pressure is removed the springs put on the brakes. A parking brake control in the cab allows the driver to let the air out of the brakes. The emergency brakes and parking brakes control the spring brakes.

Question 82
Front wheel brakes are good under all conditions. True or False?


Answer 82

Question 83
What is a dual air brake system?


Answer 83
A dual air brake system has two separate air brake systems which use a single set of brake controls. One system operates the regular brakes on the rear axle or axles. The other system operates the regular brakes on the front axle (and possibly one rear axle). Both systems supply air to the trailer (if there is one). The first system is called the primary system. The other is called the secondary system.

Question 84
What are the slack adjusters?


Answer 84
Slack adjusters control the braking power. Too much brake slack can be very hard to stop.

Question 85
How can you check slack adjusters?


Answer 85
Turn off the parking brakes so you can move the slack adjusters. Use gloves and pull hard on each slack adjuster that you can get to. If a slack adjuster moves more than about one inch where the push rod attaches to it, it probably needs adjustment.

Question 86
How can you test the low pressure warning signal?


Answer 86
Shut the engine off when you have enough air pressure so that the low pressure warning signal is not on. Turn the electrical power on and step on and off the brake pedal to reduce air tank pressure. The low air pressure warning signal must come on before the pressure drops to less than 60 psi in the air tank (or tank with the lowest air pressure, in dual air systems). If the warning signal doesn't work you could lose air pressure and you would not know it.

Question 87
What can you check that the spring brakes come on automatically?


Answer 87
Chock the wheels, release the parking brakes when you have enough air pressure to do it, and shut the engine off. Step on and off the brake pedal to reduce the air tank pressure. The parking brake knob should pop out when the air pressure falls to the manufacturer's specification (usually in a range between 20-40 psi). This causes the spring brakes to come on.

Question 88
What are the maximum leakage rates?


Answer 88
less than 2 PSI in one minute for single vehicles and less than 3 PSI in one minute for combination vehicles.
