Brakes L1

What type of energy does a car in motion produce?

• Linear

• Kinetic

• Lateral

• Static

What must a braking system be able to do?

• Stop the car and maintain control

• Lock one or more wheel to skid.

• Not let car pull away

• have drum brakes on front and disc on rear.

Which of these is a part of a braking system?

• Load compensating valve

• Servo Booster

• Wheel cylinder

• all of the above

The brake components work together to:-

• Reduce the speed of the vehicle

• To bring vehicle to a stop

• To prevent a stationary vehicle from moving

• All of the above

The service brake works on

• all four wheels

• a diagonal split n/s/f and n/s/r

• Front brakes only

• Rear brakes only

The Emergency Brake uses the:

• the front wheels

• the transmission

• Rear axle

• the parking brake

What does Hygroscopic mean

• Easily absorbs moisture

• Repels moisture

• Is not affected by moisture

• will freeze at 400° F

Typical braking systems are operated:

• Pneumatically

• Hydraulically

• Hydrolastically

• By air

Highest braking effort minus the lowest braking effort divided by highest brake effort will give you efficiency

• True

• False

Brake efficiency is worked out by:

• Highest effort minus lowest effort, divided by highest effort x 100

• Highest effort minus lowest effort divided by lowest effort x 100

• Total effort divided by vehicle weight x 100

• Average of the effort divided by weight x 100
