what effects can wet brakes cause, how can you avoid these problems
water in the brakes can cause the brakes to be weak, to apply unevenly, or to grab. Causes lack of braking power, wheel lockups, pulling to one side or the other, and jackknife
46
you should let air out of hot tires so the pressure goes back to normal, true or false
false, when they cool down the pressure may be too low
47
you can safely remove the radiator cap as long as the engine isn't overheated, true or false
false
Wait until engine has cooled. Protect hands (use gloves or a thick cloth). Turn radiator cap slowly to the first stop, which releases the pressure seal. Step back while pressure is released from cooling system. When all pressure has been released, press down on the cap and turn it further to remove it.
48
what factors determine your selection of a "safe" speed when going down a long, steep downgrade
total weight of the vehicle and cargo, length of the grade, steepness of the grade, road conditions, and weather
49
why should you be in the proper gear before starting down a hill
speed will increase on downgrades because of gravity

describe the proper braking technique when going down a long, steep downgrade
press and release
Apply the brakes just hard enough to feel a definite slowdown. When your speed has been reduced to approximately five mph below your "safe" speed, release the brakes. (This brake application should last for about three seconds.) When your speed has increased to your "safe" speed, repeat steps 1 and 2.
51

53
stopping is not always the safest thing to do in an emergency, true or false
true
54
what are some advantages of going right instead of left around an obstacle
no one is likely to be driving on the shoulder but may be passing on the left; moving right won't force anyone into oncoming traffic lane
55
what is an "escape ramp"
Escape ramps are made to stop runaway vehicles safely without injuring drivers and passengers. Escape ramps use a long bed of loose, soft material to slow a runaway vehicle, sometimes in combination with an upgrade.
56
if a tire blows out, you should put the brakes on hard to stop quickly, true or false
false, ease up on gas until vehicle slows enough to apply the brakes
57
how do you know if your vehicle has antilock brakes
check if your vehicle was manufactured after 3/1/1998; look for wheel speed sensor wires that are coming from the rear of your brakes; check for a yellow ABS malfunction lamp on the instrument panel
58
what is the proper braking technique when driving a vehicle with antilock brakes
brake until the tire starts to lock, ease up, then brake once moving again (stabbing)
59
how do antilock brakes help you
they keep the tires from locking up and not moving
60
what are some things to do at a crash scene to prevent another crash
If your vehicle is involved in the crash, try to get it to the side of the road. This will help prevent another crash and allow traffic to move.
If you're stopping to help, park away from the crash. The area immediately around the crash will be needed for emergency vehicles.
Put on your flashers. Set out reflective triangles to warn other traffic. Make sure other drivers can see them in time to avoid the crash.

121
why must air tanks be drained
to remove water and oil
122
what is a supply pressure gauge used for
tells you how much pressure is in the air tanks.
123
all vehicles with air brakes must have a low air pressure warning signal, true or false
true. It must warn you before the pressure is below 55 psi (Or one half the compressor governor cutout pressure on older vehicles.)
On large buses it is common for the low pressure warning devices to signal at 80-85 psi.
124
what are spring brakes
All trucks, truck tractors, and buses must be equipped with emergency brakes and parking brakes. They must be held on by mechanical force (because air pressure can eventually leak away). Spring brakes are usually used to meet these needs. When driving, powerful springs are held back by air pressure. If 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 spring brakes. This lets the springs put the brakes on. A leak in the air brake system, which causes all the air to be lost, will also cause the springs to put on the brakes.
125
front wheel brakes are good under all conditions, true or false
true
Front wheel braking is good under all conditions. Tests have shown front wheel skids from braking are not likely even on ice. Make sure the control is in the "normal" position to have normal stopping power.
126
what is a dual air brake system
a dual air brake system has two separate air brake systems, which use a single set of brake controls. Each system has its own air tanks, hoses, lines, etc. One typically operates the regular brakes on the rear axle or axles, the other operates the regular brakes on the front axle (and possibly one rear axle)
127
what are the slack adjusters
On S-cam brakes, it is the space between the back wheels. It is an adjusting nut on the backside of the brake drum used for adjusting the brakes.
128
how can you check slack adjusters
Park on level ground and chock the wheels to prevent the vehicle from moving. Release the parking brakes so you can move the slack adjusters. Use gloves and pull hard on each slack adjuster that you can reach. If a slack adjuster moves more than about one inch where the push rod attaches to it, it probably needs adjustment.
129
how can you test the low pressure warning signal
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 55 psi in the air tank (or tank with the lowest air pressure, in dual air systems).
130
how can you check that the spring brakes come on automatically
fan off the air pressure by stepping on and off the brake pedal to reduce tank pressure. The tractor protection valve and parking brake valve should close (pop out) on a tractor-trailer combination vehicle and the parking brake valve should close (pop out) on other combination and single vehicle types when the air pressure falls to the manufacturer’s specification (20 – 45 psi). This will cause the spring brakes to come on.
131
what are the maximum leakage rates
three pounds in one minute (single vehicle) or four pounds in one minute (combination vehicle)
132
why should you be in the proper gear before starting down a hill
speed will increase on downgrades because of gravity
133
what factors can cause brakes to fade or fail
However, brakes can fade or fail from excessive heat caused by using them too much and not relying on the engine braking effect.
134
the use of brakes on a long, steep downgrade is only a supplement to the braking effect of the engine, true or false
True
135
if you are away from your vehicle only a short time, you do not need to use the parking brake, true or false
False
Never leave your vehicle unattended without applying the parking brakes or chocking the wheels. Your vehicle might roll away and cause injury and damage.
136
how often should you drain air tanks
at the end of each day of driving
137
how should you brake when you drive a tractor-trailer combination with ABS
When you drive a tractor-trailer combination with ABS, you should brake as you always have. In other words:
Use only the braking force necessary to stop safely and stay in control.
Brake the same way, regardless of whether you have ABS on the tractor, the trailer, or both.
As you slow down, monitor your tractor and trailer and back off the brakes (if it is safe to do so) to stay in control.
There is only one exception to this procedure, if you always drive a straight truck or combination with working ABS on all axles, in an emergency stop, you can fully apply the brakes.
138
What are some hazard materials you may carry on a bus?
Buses may carry small-arms ammunition labeled ORM-D, emergency hospital supplies, and drugs. You can carry small amounts of some other hazardous materials if the shipper cannot send them any other way.
139
what 3 systems make up air brakes?
Air brakes are really three different braking systems:
The service brake system applies and releases the brakes when you use the brake pedal during normal driving.
The parking brake system applies and releases the parking brakes when you use the parking brake control.
The emergency brake system uses parts of the service and parking brake systems to stop the vehicle in a brake system failure.
