T4 ASE BRAKES (MEDIUM/HEAVY
DUTY BRAKES) EXAM
Statements of braking - *If the vehicle weight is doubled, the kinetic energy of a moving vehicle is
doubled
*Kinetic energy must be absorbed by the braking system
*the heavier the vehicle, the greater the kinetic energy when moving
Disc brakes use replaceable friction material called __________. - Pads
A locked wheel _______ to the road surface than a rolling wheel. - Has less traction
What is the purpose of any brake repair? - Restore like-new performance
True or false
The technician is not liable for damages resulting from faulty brake repair. - False
Technician A says the red brake warning lamp on the dash will light if there is a hydraulic failure or low
brake fluid level. Technician B says the red brake warning light on the dash will light if there is a fault in
the ABS. Which technician is correct? - Technician A only
The main driver-operated brakes of the vehicle are also called _________ brakes. - *Base
*Foundation
True or false
Brake fluid must not boil or damage vehicle painted surfaces. - False
The backing plate is a component of which type brake assembly? - Drum
, True or false
The technician must preform the FMVSS test on every vehicle he or she repairs - False
What are the six brake system categories? - 1. Apply system
2. Boost system
3 .Hydraulic System
4. Wheel brakes
5. Brake balance control system
6. Brake warning lights
What can the driver do to reduce the possibility of brake fade caused by heat? - Select the lower
transmission gear
Technician A says that the thicker or heavier the disc brake rotor, the more heat can be absorbed.
Technician B says that the faster the vehicle is traveling when the brakes are applied, the greater the
amount of heat created in the break system. Which is correct? - Both Technicians are correct
Types of brake fade - *Lining Fade
*Mechanical Fade
*Gas fade
Brake fade caused by water can occur __________________ - Whenever driving through water puddles
or during severe rainstorm
The friction between two surfaces is affected by - *Friction material
*Surface finish
*Heat
Maximum deceleration rates for a typical passenger car or light truck is __________. - 2
