1. Most 1995 and newer vehicles use which type of wheel
bearings on non-drive wheels?
Correct Answer: Sealed, non-serviceable wheel
bearings.
Expert Rationale: Modern non-drive wheel assemblies
commonly use sealed bearing units that are factory
lubricated and designed to operate without periodic
cleaning, repacking, or adjustment. When the bearing
becomes worn or damaged, the complete bearing
assembly is typically replaced.
2. To test a vacuum power brake booster in the vehicle,
you should pump the brake pedal at least four times,
hold the brake pedal depressed, and start the engine.
, The brake pedal should:
Correct Answer: Drop slightly and remain firm.
Expert Rationale: Pumping the pedal removes stored
vacuum assist. When the engine starts, vacuum should be
applied to the booster, causing the pedal to move
downward slightly. A noticeable drop indicates that the
booster is receiving and applying vacuum assistance.
3. You are installing a set of brake-shoe linings that are
not the same length. Traditionally, the primary shoe
lining is:
Correct Answer: Smaller and goes toward the front of
the car.
Expert Rationale: In a traditional duo-servo drum-brake
arrangement, the primary shoe is positioned toward the
front and normally has the shorter lining. The secondary
shoe is positioned toward the rear and generally has the
longer lining.
4. A cracked or torn vacuum diaphragm in a brake
power booster would most likely cause:
Correct Answer: A hard pedal feel requiring very high
pedal effort to stop.
Expert Rationale: A damaged booster diaphragm can
, prevent the booster from maintaining the vacuum
differential needed to assist braking. Without adequate
power assistance, the driver must apply substantially
greater pedal force to produce normal braking.
5. A mechanic finds gear lube inside both rear brake
drums on a rear-wheel-drive vehicle. What is the
most likely cause?
Correct Answer: A plugged axle vent.
Expert Rationale: A restricted axle vent can allow
pressure to build inside the axle housing as the lubricant
heats and expands. The increased pressure can force gear
oil past axle seals and into the brake assemblies.
6. Which incorrect service procedure will cause brake
lock-up?
Correct Answer: Master-cylinder pushrod adjusted too
long.
Expert Rationale: An excessively long pushrod can
prevent the master-cylinder piston from fully returning.
This can block the compensating port, preventing
hydraulic pressure from releasing properly and
potentially causing the brakes to remain applied.
, 7. Which describes the proper way to depressurize an
ABS system?
Correct Answer: Pump the brake pedal at least 25
times, or more depending on the manufacturer's
recommendation, with the ignition off.
Expert Rationale: ABS hydraulic units can retain
significant pressure even after the vehicle is switched off.
Repeatedly pumping the pedal with the ignition off helps
discharge stored hydraulic pressure before service.
Manufacturer-specific procedures should always take
precedence.
8. The rear brakes are dragging after new linings were
installed and the drums were machined. The most
likely cause is:
Correct Answer: The technician used the parking brake
to adjust the shoes and the cable is stuck.
Expert Rationale: A seized or improperly adjusted
parking-brake cable can prevent the rear shoes from fully
returning to their released position. This leaves the shoes
contacting the drums and produces brake drag and heat.
9. When turning brake drums:
Correct Answer: Use a dampening strap to reduce
