CORRECT ANSWERS) /ALREADY GRADED A+
Question 1
Most 1995 & newer vehicles use which of the following types of wheel
bearings on non-drive wheels?
A) Tapered roller bearings (serviceable)
B) Loose ball bearings
C) Adjustable caged bearings
D) Sealed non-serviceable
E) Open ball bearings with grease caps
Correct Answer: D) Sealed non-serviceable
Rationale: For 1995 and newer vehicles, sealed, non-serviceable
wheel bearings are a common design choice for non-drive wheels,
meaning they are replaced as a complete unit rather than being
disassembled and repacked.
Question 2
To test a vacuum power brake booster in the vehicle, you should pump the
brake pedal at least 4 times, hold the brake pedal depressed, and start the
engine. The brake pedal should:
A) Rise slightly and remain firm.
B) Remain at the same position.
C) Drop significantly to the floor.
D) Drop slightly and remain firm.
E) Become completely hard immediately.
Correct Answer: D) Drop slightly and remain firm
Rationale: This test checks for proper booster operation. When the
engine starts and vacuum assistance becomes available, the pedal
should drop slightly due to the added boost, then remain firm as
hydraulic pressure is maintained.
,Question 3
You are installing a set of brake shoe linings that are not the same length in a
drum brake system. Traditionally, the primary shoe lining is:
A) Larger and goes towards the rear of the car.
B) Smaller and goes towards the front of the car.
C) The same size as the secondary shoe.
D) Used only on the parking brake.
E) Always installed on the top of the assembly.
Correct Answer: B) Smaller and goes towards the front of the car.
Rationale: In drum brake systems with different length linings, the
primary shoe, which is typically smaller, is positioned towards the
front of the vehicle. The larger secondary shoe is at the rear for
greater braking force.
Question 4
A cracked or torn vacuum diaphragm in a brake power booster would most
likely cause:
A) A spongy pedal feel.
B) Excessive brake fluid consumption.
C) A hard pedal feel requiring very high pedal effort to stop.
D) The brake pedal to stick to the floor.
E) Reduced engine vacuum causing a rich fuel mixture.
Correct Answer: C) A hard pedal feel requiring very high pedal effort
to stop
Rationale: A cracked or torn vacuum diaphragm prevents the booster
from holding vacuum, leading to a loss of power assist. This results
in the driver having to exert much more effort on the pedal to
achieve braking.
Question 5
A mechanic finds gear lube inside both rear brake drums on a rear-wheel-
drive vehicle. What is the most likely cause of this problem?
,A) Worn wheel cylinders.
B) A leaking master cylinder.
C) A plugged axle vent.
D) Worn brake lines.
E) A defective proportioning valve.
Correct Answer: C) A plugged axle vent
Rationale: If gear lube is found in both rear brake drums, a plugged
axle vent can cause pressure to build up in the differential, forcing
gear lube past the axle seals and into the brake drums.
Question 6
Which of the following incorrect service procedures will cause brake lock-up?
A) Master cylinder push rod adjusted too short.
B) Air in the brake lines.
C) Master cylinder push rod adjusted too long.
D) Excessively worn brake pads.
E) A leaking wheel cylinder.
Correct Answer: C) Master cylinder push rod adjusted too long
Rationale: If the master cylinder push rod is adjusted too long, it can
prevent the primary cup from returning past the compensating port,
trapping pressure in the hydraulic system and causing the brakes to
drag or lock up.
Question 7
Which of the following describes the proper way to depressurize an ABS
system?
A) Disconnect the battery and wait 5 minutes.
B) Open the bleeders on all four wheels simultaneously.
C) Pump the brake pedal at least 25 times (or more, depending on the
manufacturer's recommendation) with the ignition off.
D) Loosen the brake lines at the master cylinder.
E) Engage and disengage the parking brake repeatedly.
, Correct Answer: C) Pump the brake pedal at least 25 times (or more,
depending on the manufacturer's recommendation) with the ignition
off.
Rationale: Many ABS systems, especially those with an accumulator,
require the brake pedal to be pumped numerous times with the
ignition off to release any stored hydraulic pressure before
servicing.
Question 8
The rear brakes are dragging after having new linings installed and the
drums machined. The most likely cause is the:
A) Technician did not bleed the brakes properly.
B) Technician used a brake spoon to adjust the shoes too tightly.
C) Technician failed to clean the drums.
D) Technician used the parking brake to adjust shoes and the cable is stuck.
E) Wheel cylinders are seized.
Correct Answer: D) Technician used the parking brake to adjust shoes
and the cable is stuck
Rationale: Using the parking brake to adjust drum brakes is an
incorrect procedure. If the parking brake cable becomes stuck or
improperly adjusted during this process, it can cause the shoes to
remain engaged, leading to dragging brakes.
Question 9
When turning brake drums:
A) Always use maximum cutting depth to save time.
B) Omit the dampening strap for a smoother finish.
C) Do not exceed the maximum diameter specification.
D) Use a dampening strap to reduce chatter.
E) Turn both drums to the smallest possible diameter for best performance.
Correct Answer: D) Use a dampening strap to reduce chatter
Rationale: A dampening strap or band is used around the drum
