BOOK 8:MODULE 5 Apparatus Characteristics That Can Contribute To Accidents

Question 1

Improper use or excessive braking will cause the brakes to heat up. This is?

Answer 1

Brake fade

Question 2

Brake fade:

As heat builds up, the _____ on the brake shoes begin to melt. As it melts, it turns to liquid that lubricates the space between the ___ and the ___ causing the brake drums to ___. This same heat will cause the drums to expand causing the brake shoes to travel ____ to reach the brake drum. It will be necessary to increase ________in order to stop or slow the vehicle.

Answer 2

Lining
Shoe and the drum
Glaze
Farther
Pedal pressure

Question 3

____ ___are much more susceptible to brake fade due to the fact that most of the total surface is in contact with the brake shoes at any one time.

Answer 3

Drum brakes

Question 4

Pads on a disk brake system make contact with a ___percent of the disc surface, therefore allowing a major percent of the disc to be _____. Disc brake systems actually become more ______ as they get hot and expand, making better contact with the pads.

Answer 4

Small percent
Cooler
Efficient

Question 5

Most heavy vehicles use ___ brakes rather than hydraulic or mechanical brakes.

Answer 5

Air

Question 6

Depressing the brake pedal opens a valve that releases compressed air from a tank. The pressurized air reaches the rakes through the air lines and forces the brake shoes against the brake drum (or-brake pads against the disc). Depending on the type of vehicle, it will take between __ to _ second for the air to reach the brakes after you press the foot pedal. This is know as?

Answer 6

1/4 to 1 second

Brake lag

Question 7

Tire pressure should be checked when the tires are ___ and maintained at recommended pressures.

Answer 7

Performance
Accident

Steering braking and cornering
Cold

Question 8

Answer 8

Rain
Dirt

Rubber and the road

Question 9

Proper tread depth reduces the chance of ______ in wet conditions and _____ traction in dry conditions, therefore correct tread depth must be maintained in accordance with L.A.F.D. specifics.

Answer 9

Hydroplaning

Increased traction

Question 10

Every vehicle has its own ____ _____. The good driver knows where they are and how to compensate accordingly.

Answer 10

Approaching _______ at greater speed.
Losing control of the vehicle due to unsafe surface street _____ or ____ conditions.

Answer 13

Less time
Intersections
Speed or road conditions

Question 14
