ASE Mechanics Brake Systems & Suspension — Questions and Answers
Question 1: What is the primary function of the anti-lock braking system (ABS)?
- To increase braking distance
- To prevent wheel lock-up and improve control (Correct answer)
- To disable manual braking systems
- To increase tire wear
Correct answer: To prevent wheel lock-up and improve control
ABS prevents the wheels from locking up during braking, improving steering control and reducing the risk of skidding.
Question 2: What is a common symptom of worn brake pads?
- Soft and silent braking
- High-pitched squealing noise (Correct answer)
- Braking distance decreases
- No effect on braking performance
Correct answer: High-pitched squealing noise
Worn brake pads often produce a high-pitched squealing noise, indicating the need for replacement before rotor damage occurs.
Question 3: What component connects the wheels to the suspension system?
- Brake rotor
- Control arms (Correct answer)
- Exhaust manifold
- Alternator
Correct answer: Control arms
The control arms link the wheels to the vehicle's frame, allowing for controlled movement and suspension articulation.
Question 4: What is the purpose of a shock absorber in a suspension system?
- To increase vehicle bouncing
- To dampen suspension movement and improve stability (Correct answer)
- To replace the coil springs
- To decrease braking efficiency
Correct answer: To dampen suspension movement and improve stability
Shock absorbers dampen the movement of the suspension springs, reducing excessive bouncing and improving vehicle stability.
Question 5: What can cause uneven tire wear in a vehicle?
- Properly inflated tires
- Wheel misalignment or worn suspension parts (Correct answer)
- Balanced wheel rotation
- Regular brake pad replacement
Correct answer: Wheel misalignment or worn suspension parts
Uneven tire wear is often a result of misaligned wheels, worn suspension components, or incorrect tire pressure.
Question 6: Why is brake fluid important for a vehicle’s braking system?
- To lubricate the brake pads
- To transfer force for effective braking (Correct answer)
- To cool down the engine
- To reduce vehicle weight
Correct answer: To transfer force for effective braking
Brake fluid transfers force from the brake pedal to the braking components, allowing for effective stopping power.
