Rationale
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
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
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
C : low power steering fluid
why : low power steering fluid can cause the booster to provide very little if any boost
Which of the following could cause excessive noise braking?
a. worn wheel cylinders
b. worn caliper pistons
c. seized caliper slides
d. missing clips
D : missing clips
why : missing anti-rattle clips could cause excessive noise while braking
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
C : scan tool
,why : a scan tool or oscilloscope can be used to test a signal from a digital when speed
sensor
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
C : a bypassing master cylinder
why : a bypassing master cylinder would cause a low pedal and would not cause a loss
of fluid
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
D : neither A OR B
why : neither technician is correct. this style of pin should be installed with a torx or hex
head socket
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
A : only A
why : only tech A is correct. a hydro-boost system uses hydraulic pressure to create
boost
A disc brake caliper is dragging. All of the following could be the cause EXCEPT
a. binding pins
b. sticking piston
c. binding caliper
d. worn brake pads
D : worn brake pads
why : worn brake pads will not cause the brakes to drag
,Which operation is being performed in the illustration? ( pg. 48 )
a. wheel cylinder bleeding
b. brake caliper bleeding
c. master cylinder bleeding
d. master cylinder pressure test
C : master cylinder bleeding
why : the master cylinder is being bleed prior to installation
The rear wheels of a front wheel drive car lockup during heavy breaking.
Technician A says this could be cause by faulty proportioning valve. Technician
B says this could be caused by a faulty brake booster. Who is correct?
a. A only
b. B only
c. Both A & B
d. Neither A or B
A : A only
why : tech A is correct. a faulty proportioning valve could cause the pressure to the rear
wheels to be too high and lock the wheels during hard braking
There is a loud growling noise only when the vehicle is steered to the right while
driving. Which of the following could be the cause?
a. work left front brakes
b. worn wheel bearing
c. worn right front brakes
d. sticking brake caliper
B : worn wheel bearing
why : this is a typical wheel bearing noise
A spongy pedal can be the result of:
a. leaking wheel cylinders
b. broken return springs
c. contaminated linings
d. seized wheel cylinder pistons
A : leaking wheel cylinders
why : a spongy pedal can result from air in the hydraulic system. leaking wheel cylinders
could allow air to get into the hydraulic system and result in a spongy pedal
A vehicle has a wheel speed sensor diagnostic trouble code. Which of the
following is the LEAST LIKELY cause?
a. faulty wheel speed sensor
b. cracked wheel speed sensor reluctor ring
, c. a tire with the incorrect height
d. a tire with the incorrect width
D : a tire with the incorrect width
why : the width of the tire will not affect the wheel speed sensor signal
A vehicle has a squeak only when applying the breaks. Which of the following
could be the cause?
a. aerated brake fluid
b. water contaminated break fluid
c. worn brake pads
d. worn wheel bearings
C : worn brake pads
why : worn pads can cause a squeak when applying the brakes
During a moderate brake pedal application, with the engine running, what would
be considered a normal pressure reading on the inlet pressure gauge? ( pg. 49 )
a. 100 psi
b. 900 psi
c. 3,000 psi
d. 5,000 psi
B : 900 psi
why : this would be normal
Which of the following would be the most normal end-play specification for a set
of tapered roller front wheel bearings?
a. 0.0001"-0.0005" ( 0.00254 mm - 0.0127 mm )
b. 0.0010"-0.0050" ( 0.0254 mm - 0.127 mm )
c. 0.0100"-0.0500" ( 0.254 mm - 1.27 mm )
d. 0.1000" - 0.5000" ( 2.54 mm - 12.7 mm )
B : 0.0010" - 0.0050" ( 0.0254 mm - 0.127 )
why : this is the correct specification
Brake chatter can be caused by:
a. seized star-wheel adjuster
b. seized wheel cylinder
c. contaminated linings
d. switched primary and secondary shoes
C : contaminated linings
why : contaminated linings could cause the brake shoes to stick and slip, which would
