1. During a state inspection, a technician notices brake fluid leaking from the
rear wheel area. The brake pedal feels spongy. What is the MOST likely cause?
A. Worn brake pads
B. Faulty proportioning valve
C. Leaking wheel cylinder
D. Warped brake rotor
Answer: C. Leaking wheel cylinder
Rationale: Wheel cylinders are common leak points in drum brake systems and
cause fluid loss and a spongy pedal.*
2. A vehicle pulls sharply to the right when braking. Inspection shows uneven
front brake pad wear. What is the MOST likely cause?
A. Low brake fluid
B. Seized left caliper
C. Warped rotors
D. Faulty ABS module
,Answer: B. Seized left caliper
Rationale: A seized caliper prevents equal braking force, causing pull toward the
functioning side.*
3. During a road test, the brake pedal slowly sinks while steady pressure is
applied. No external leaks are found. What component has MOST likely failed?
A. Brake booster
B. ABS sensor
C. Master cylinder
D. Brake hoses
Answer: C. Master cylinder
Rationale: Internal seal failure allows fluid to bypass, causing pedal fade.*
4. A vehicle fails state inspection due to excessive brake pedal travel. Which
condition MOST commonly causes this failure?
A. Contaminated brake fluid
B. Air in hydraulic lines
C. Worn rotors
D. Overinflated tires
Answer: B. Air in hydraulic lines
Rationale: Air compresses, increasing pedal travel.*
5. A technician measures rotor thickness and finds it below the stamped
minimum specification. What is the correct repair?
A. Resurface the rotor
B. Reinstall and monitor
C. Replace the rotor
D. Adjust brake pads
, Answer: C. Replace the rotor
Rationale: Rotors below minimum thickness must be replaced to meet safety
standards.*
6. While inspecting a drum brake system, the technician notices brake shoes
soaked in fluid. What action is REQUIRED?
A. Clean shoes and reinstall
B. Adjust shoe clearance
C. Replace shoes and fix leak
D. Bleed the brake system only
Answer: C. Replace shoes and fix leak
Rationale: Brake linings contaminated with fluid cannot be safely reused.*
7. A customer complains of brake pulsation at highway speeds. What inspection
tool BEST confirms the cause?
A. Micrometer
B. Torque wrench
C. Dial indicator
D. Brake pressure gauge
Answer: C. Dial indicator
Rationale: A dial indicator checks rotor runout, a common cause of pulsation.*
8. A hard brake pedal with normal stopping distance MOST likely indicates
failure of which component?
A. Master cylinder
B. Brake booster
C. Proportioning valve
D. ABS module
