1. A drum is chattering on the brake lathe. This could be a result of
a. failure to install the dampening belt
b. cutting too slowly
c. dull cutting blades
d. cutting speed too fast
Answer: A : failure to install the dampening belt
why : a missing dampening belt could cause the drum to vibrate while on the lathe.
this vibration can cause the drum to bounce on the cutting tip and make a chattering
noise
2. A vehicle equipped with a hydro-boost brake system has a hard pedal with
little braking action. Which of the following could be the cause?
a. low brake fluid
,b. air in the brake fluid
c. low power steering fluid
d. an overtightened power steering belt
Answer: C : low power steering fluid
why : low power steering fluid can cause the booster to provide very little if any boost
3. Which of the following could cause excessive noise braking?
a. worn wheel cylinders
b. worn caliper pistons
c. seized caliper slides
d. missing clips
Answer: D : missing clips
why : missing anti-rattle clips could cause excessive noise while braking
4. A vehicle equipped with a "hill holding" option has an ABS code. Which tool
would most likely be used to check the wheel speed sensor?
a. AC volt meter
b. Ohm meter
c. Scan tool
d. Ammeter
Answer: C : scan tool
why : a scan tool or oscilloscope can be used to test a signal from a digital when
speed sensor
,5. The brake system has a soft, sinking pedal with the engine running. The
brake fluid level is at the correct height. Which of the following could be the
cause?
a. a restricted vacuum hose
b. a leaking master cylinder
c. a bypassing master cylinder
d. a stuck open vacuum check valve
Answer: C : a bypassing master cylinder
why : a bypassing master cylinder would cause a low pedal and would not cause a
loss of fluid
6. Technician A says the pins should be driven in with a brass hammer.
Technician B says the pins should be lubricated with brake fluid. Who is
correct? ( pg. 47 )
a. A
b. B
c. A & B
d. neither A OR B
Answer: D : neither A OR B
why : neither technician is correct. this style of pin should be installed with a torx or
hex head socket
7. Technician A says a hydro-boost system can use the power steering pump
to operate the booster. Technician B says a hydro-boost system can use
engine vacuum to operate the booster. Who is correct? ( pg. 47 )
a. A
, b. B
c. A & B
d. neither A & B
Answer: A : only A
why : only tech A is correct. a hydro-boost system uses hydraulic pressure to create
boost
8. A disc brake caliper is dragging. All of the following could be the cause
EXCEPT
a. binding pins
b. sticking piston
