For air brake system in good condition the air compressor start pumping at about ____ P.S.I	100psi
If your vehicle has an alcohol evaporator, it is there to:	Reduce the risk of ice in air brake valves in cold weather
Some air brake systems have an alcohol evaporator. What happen if you don't keep the unit filled with alcohol?	Ice will form in the storage tanks and cause the brakes to ----
The safety valve is set automatically to reduce pressure to _____ PSI	150
The brake pedal in an air brake system:	Controls the air pressure applied to put on the brakes.
Repeatedly pressing and releasing ( Fanning the brake pedal may result in:	A loss of air pressure
The most common type of foundation brake found on heavy vehicles is the:	S-cam drum
S-cam.	Forces the brake shoes against the inside of the brake drum.
When the brakes are applied the brakes shoes or linings are pressed against the:	Brake drums or disc.
All air brake equipped vehicles have:	A supply pressure gauge.
The application pressure gauge shows how much air pressure you:	Are applying to the brakes.
The driver must be able to see a warning before air pressure in the service air tanks falls below _____PSI	60
Stop light switch:	Turns on the brake lights to warn drivers behind you.
Under normal conditions in order to engage the parking brakes the driver must first:	Make sure the air brake system is fully pressurized.
The braking power of the spring brakes;	Depends on the service brakes being in adjustment.
The parking or emergency brake on trucks and buses can only be held on by _____	Spring
If your truck or bus has dual parking control valves, you can use pressure from a separate tank to	Release the spring emergency/parking brakes to move a short distance
If the springs brakes are on you should push the brake pedal.	Never
The most important thing to do when the low air warning comes on:	Stop and safely park as soon as possible
YOur vehicle has a dual air brake system. If a low pressure warning comes on for the secondary system; you should:	Bring the vehicle to a safe stop and continue only when the system is fixed
If your truck has a dual air system and one of the systems is low pressure.	Either the front or rear brakes will not be fully operational.
To check the free play of manual slack adjusters on S-cam brakes you should park on:	Level ground, chock the wheels, and turn off the parking brakes.
The slack adjuster probably needs to be adjusted if it moves more than, about____ inch. When you pull hard on it.	1
How should you check that the spring brakes come on when air pressure in the system drops below a certain level:	Park on a level ground,chock the wheel release parking brake - you have enough air
If your truck has a properly functioning dual air brake system minimum size air tanks, the pressure should build from 85 to 100 PSI in ____	45
The air loss rate of straight truck or bus with the engine of air brakes on should not be more than:	3 PSI in 1 min
If air pressure does not go back to normal in the correct -- then:	The air pressure may drop too low during driving requiring dependency
The air compressor should stop pumping at about ______	125
You are driving a truck or bus with a dual air brake system the pressure in each system should be at least ____ PSI	100
How should you check that your service brakes are working properly?	Park on level ground, waits for normal air pressure, and release the parking brake firmly using the brake pedal.
To test air service brakes you should:	Brake firmly when slowly moving forwards.
If you must make an emergency stop, brake so you:	Can steer and your vehicle stay in a straight line
Emergency controlled braking is used when:	Applying the brakes as hard as you can without locking
Emergency stab braking is when you:	Brake as hard as you can; release the brakes when the wheel locks up
Under ideal conditions a truck with air brakes going 55mph requires a stopping distance of:	More than 300ft.
The total stopping distance for air brakes is longer than the hydraulic brakes due to ___ distance:	Brake lag
The air brake lag distance at 55mph on dry pavement ads about ____ feet to the stopping distance.	32
Excessive use of service brakes result in over heating which can lead to:	Expansion of the brake drums.
The use of air brakes on a long or steep downgrade under normal conditions is only a supplement to:	The braking effect of the engine.
The proper method of breaking while going down long or steep curves after selecting the proper gear is to brake until your speed drops to ___ mph below the safe speed then release your brakes.	5
You are driving down a steep downhill grade and you have checked for a safe speed of 40mph. Apply the service brake until your speed drops to ___ mph.	35
If your truck or bus has dual air brake system and the low air warning comes on for only one system. What should you do?	Stop by the road and park. Continue on after the system is fixed.

An air pressure system is fully charged at ______ PSi	125
Air braking takes more time than hydraulic braking because air:	Takes more time to flow threw the lines than hydraulic fluid.
