1. Most 1995 & newer vehicles use which of the following types of wheel bearings on non-drive
wheels?
A) Serviceable tapered roller bearings
B) Sealed non-serviceable
C) Ball bearings requiring regular grease
D) Adjustable cup and cone bearings
Answer: B
EXPLANATION: Most modern vehicles (1995 and newer) use sealed, non-serviceable wheel
bearings on non-drive wheels to reduce maintenance and improve reliability by preventing
contamination.
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 then stay firm
B) drop slightly and remain firm
C) remain the same and then drop
D) rise and then drop quickly
Answer: B
EXPLANATION: When the engine starts, the vacuum assists the booster, causing the brake pedal
to drop slightly while remaining firm, indicating proper booster operation.
3. You are installing a set of brake shoe linings that are not the same length. Traditionally, the
primary shoe lining is:
A) Longer and goes towards the rear
B) Smaller and goes towards the front of the car
C) Larger and goes towards the front of the car
D) The same length on both shoes
Answer: B
, EXPLANATION: The primary shoe is typically smaller and is installed toward the front of the
vehicle to improve initial braking and adjust for drum rotation.
4. A cracked or torn vacuum diaphragm in a brake power booster would most likely cause:
A) a soft pedal feel with little braking power
B) a hard pedal feel requiring very high pedal effort to stop
C) the brake pedal to sink slowly
D) the brake pedal to pulsate under pressure
Answer: B
EXPLANATION: The vacuum diaphragm assists braking force. If damaged, the driver must apply
much more pedal effort, causing a hard brake pedal feel.
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) Leaking wheel cylinder
B) A plugged axle
C) Faulty axle seals
D) Overfilled brake fluid reservoir
Answer: B
EXPLANATION: A plugged axle causes the lubricant to be forced past the axle seals into the
brake drums.
6. Which of the following incorrect service procedures will cause brake lock-up?
A) Master cylinder push rod adjusted too short
B) Master cylinder push rod adjusted too long
C) Using wrong brake fluid
D) Bleeding brakes improperly
Answer: B
EXPLANATION: If the master cylinder push rod is too long, it applies continuous pressure to the
brakes, causing lock-up.
7. Which of the following describes the proper way to depressurize an ABS system?
A) Pump the brake pedal 10 times with the ignition on
B) Pump the brake pedal at least 25 times (or more, per manufacturer) with ignition off
C) Hold the brake pedal while starting the engine
D) Use a scan tool to release pressure only
Answer: B
EXPLANATION: Depressurizing the ABS system requires pumping the brake pedal repeatedly
with ignition off to release residual pressure safely.
