1. What is the primary purpose of a vehicle braking system?
A. To increase engine power
B. To reduce vehicle speed or stop the vehicle
C. To improve fuel efficiency
D. To stabilize steering
Correct Answer: B – The braking system converts kinetic energy into
heat through friction to slow or stop the vehicle safely.
2. Which component converts hydraulic pressure into mechanical
force at the wheel?
A. Master cylinder
B. Brake booster
C. Caliper or wheel cylinder
D. Proportioning valve
Correct Answer: C – Calipers (disc) or wheel cylinders (drum) apply force
to pads or shoes.
3. What fluid type is most commonly used in hydraulic brake systems?
,A. Power steering fluid
B. DOT brake fluid
C. Transmission fluid
D. Engine oil
Correct Answer: B – DOT-rated brake fluid is designed to withstand high
temperatures and pressure.
4. Which brake fluid characteristic is most critical for safety?
A. Color
B. Boiling point
C. Viscosity at room temperature
D. Odor
Correct Answer: B – A high boiling point prevents vapor lock and brake
failure.
5. A soft or spongy brake pedal usually indicates:
A. Worn brake pads
B. Air in the brake lines
C. Faulty ABS sensor
D. Warped rotors
Correct Answer: B – Air compresses, reducing hydraulic effectiveness.
6. What component assists braking by using engine vacuum?
A. Master cylinder
B. Proportioning valve
,C. Brake booster
D. ABS module
Correct Answer: C – The brake booster reduces pedal effort using
vacuum assistance.
7. Which braking system uses shoes and drums?
A. Disc brake system
B. Hydraulic assist system
C. Drum brake system
D. ABS system
Correct Answer: C – Drum brakes rely on brake shoes pressing outward
against a drum.
8. What is the main advantage of disc brakes over drum brakes?
A. Lower cost
B. Better heat dissipation
C. Longer stopping distance
D. Reduced pedal pressure
Correct Answer: B – Disc brakes cool more efficiently, reducing brake
fade.
9. ABS primarily prevents which condition during braking?
A. Brake noise
B. Brake fade
C. Wheel lock-up
D. Fluid leaks
, Correct Answer: C – ABS prevents wheels from locking, maintaining
steering control.
10. Which ABS component monitors wheel speed?
A. Hydraulic pump
B. Control module
C. Wheel speed sensor
D. Brake booster
Correct Answer: C – Wheel speed sensors detect changes in wheel
rotation.
11. A pulsating brake pedal during hard stops usually indicates:
A. Normal ABS operation
B. Low brake fluid
C. Master cylinder failure
D. Air in lines
Correct Answer: A – ABS causes pedal pulsation during activation.
12. What causes brake fade?
A. Cold brake components
B. Excessive heat
C. Low tire pressure
D. Faulty wheel bearings
Correct Answer: B – Heat reduces friction efficiency between braking
surfaces.
