<BRAND NEW VERSION>
1. Hydraulic system - ANSWER ✔ Components (such as the brake lines and
master cylinder) that transfers power from the brake pedals to either disc or
drum brakes.
2. Mechanical Foundation System - ANSWER ✔ Components (such as discs
and pads or drums and shoes) that creates the friction required to stop the
vehicle.
3. Electronic system - ANSWER ✔ Components that notify the driver of a
failure in the brake system. In anti-lock brake (ABS) systems, electrical
system components work to prevent tire skidding.
4. A spongy brake pedal may be caused by:
a. ABS Diagnostic Trouble Code set
b. Frozen caliper piston
c. Defective metering valve.
d. Air in hydraulic system - ANSWER ✔ D.
5. This question has the word EXCEPT. For this question, look for the choice
that could NOT cause the described situation. Read the entire question
carefully before choosing your answer. A vehicle has a very erratic brake
pulling concern while applying the brakes. All of the following items could
cause this erratic pull EXCEPT:
a. Excessive tire pressure
b. Four-wheel alignment
c. Seized caliper piston on the other side
, d. Steering gear problem - ANSWER ✔ A.
6. The brakes are being bled on an older vehicle equipped with a quick take up
valve in the master cylinder. Technician A says the quick take up valve must
be depressed. Technician B says the brakes on this vehicle cannot be bled.
Who is right?
a. A only
b. B only
c. Both A and B
d. Neither A nor B - ANSWER ✔ D.
7. A power assist brake booster push rod that is to short will cause which of the
following?
a. Excessive brake drag
b. Brake system to be inoperative
c. Excessive brake pedal travel
d. Brake light is illuminated - ANSWER ✔ C.
8. A hydraulic brake line is leaking. Which of these is the correct repair?
(A) Cut out the bad section and replace with new steel tubing
using compression fittings.
(B) Replace the leaking line with double-flared seamless copper
tubing.
(C) Cut out the bad section and replace with single-flared steel
tubing using flare nuts and unions.
(D) Replace the leaking line with double-flared steel tubing. -
ANSWER ✔ D.
9. The drag on a vehicle's drum brakes increases after each application until
they lockup. Bleeding the system restores normal operation for a short time;
then drag increases until the brakes lockup again. Which of these could be
the cause?
(A) A blocked compensating port
(B) A blocked breather port
(C) Wrong brake shoe adjustment
, (D) Weak brake shoe return springs - ANSWER ✔ A.
10.With the brakes applied, the pedal moves down slightly when the engine is
started on a vehicle with power brakes.
Technician A says that the cause could be a leaking power brake booster
diaphragm.
Technician B says that the cause could be a stuck closed check valve on the
power brake booster manifold.
Who is right?
(A) A only
(B) B only
(C) Both A and B
(D) Neither A nor B - ANSWER ✔ D.
11.The caliper piston seal is leaking. What would MOST LIKELY be the
result?
a. the ABS light would start to flash
b. the traction control light would start to flash
c. the brake pedal would become very hard
d. the brake pedal would become very soft - ANSWER ✔ D : the brake
pedal would become very soft
why : the brake pedal would become soft because as the fluid got low, air
would enter the system
12.A vehicle pulls right while braking. The MOST LIKELY cause would be:
a. seized left caliper slides
b. faulty metering valve
c. seized right rear wheel cylinder
d. faulty master cylinder - ANSWER ✔ A : seized left caliper slides
, why : seized left caliper slides would cause a lack of braking force on the
left side. the higher braking force on the right side would cause the vehicle
to pull to the right
13.The pressure differential valve lights the red brake warning light when:
a. the parking brake pedal in depressed
b. there is an ABS code
c. there is a pressure imbalance
d. the brake fluid is low - ANSWER ✔ C : there is a pressure imbalance
why : a pressure differential will cause the switch to illuminate the light
14.Two technicians are discussing traction control systems. Technician A says
that some traction control strategies do not use the brakes to control wheel
spin. Technician B says that a fault in the ABS does not affect traction
control. Who is right?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - ANSWER ✔ The correct answer is A.
Some manufacturers reduce power to the spinning wheel
by retarding the ignition timing, cutting off fuel injection
to certain cylinders and/or mechanically closing the
throttle, and may only apply the brakes if the wheel
continues to spin. Technician B is wrong because the
TCS uses the same components as the ABS if there is a
fault in the ABS the TCS is turned off as well.
15.When rough machining a brake drum, the depth of cut and spindle feed rate
should be:
A. 0.010-0.015-in. at high feed rate
B. 0.010-0.015-in. at low feed rate
C. 0.005-in. at high feed rate
D. 0.005-in. at low feed rate - ANSWER ✔ The correct
answer is A. The tool depth on a rough cut, where a large
amount of material is removed to initially clean the drum,
is usually about 0.010-in to 0.015-in. at a high spindle
feed rate.
