- 1.
What is the purpose of a brake caliper?
- A.
Engage brake pads
- B.
Store brake fluid
- C.
Generate brake pressure
- D.
Adjust brake balance
Correct Answer
A. Engage brake padsExplanation
The purpose of a brake caliper is to engage brake pads. Brake calipers are a crucial component of the braking system in many vehicles. They house the brake pads and, when activated, apply pressure to the brake pads, causing them to make contact with the brake rotor (in disc brake systems) or the brake drum (in drum brake systems).Rate this question:

Which type of brake fluid is commonly used in most modern vehicles?
- A.
DOT-3
- B.
DOT-4
- C.
DOT-5
- D.
DOT-5.1
Correct Answer
B. DOT-4Explanation
DOT-4 brake fluid is commonly used in modern vehicles due to its higher boiling point and compatibility with various brake systems.Rate this question:

- 3.
What component is responsible for transmitting the force from the brake pedal to the brake system?
- A.
Brake booster
- B.
Master cylinder
- C.
Brake rotor
- D.
Brake caliper
Correct Answer
B. Master cylinderExplanation
system is the master cylinder. The master cylinder is a critical part of the hydraulic braking system. When you press the brake pedal, it creates hydraulic pressure in the master cylinder, which is then transmitted through the brake lines to the brake calipers (in disc brake systems) or wheel cylinders (in drum brake systems).Rate this question:

Which type of brake is typically used in emergency or parking situations?
- A.
Disc brake
- B.
Drum brake
- C.
Hand brake
- D.
Anti-lock brake
Correct Answer
C. Hand brakeExplanation
The type of brake typically used in emergency or parking situations is the hand brake, also known as the parking brake or emergency brake. It is a separate braking system from the primary hydraulic braking system (which may include disc brakes or drum brakes). The hand brake is manually operated and is primarily used to secure the vehicle in a stationary position, especially when parking on slopes or during emergency situations.Rate this question:

What is the purpose of the brake fluid reservoir?
- A.
Generate hydraulic pressure
- B.
Store extra brake fluid
- C.
Cool the brakes
- D.
Collect excess brake fluid
Correct Answer
D. Collect excess brake fluidExplanation
The brake fluid reservoir collects excess brake fluid and compensates for fluid displacement as the brake pads wear down.Rate this question:

- 6.
Which component is responsible for preventing the wheels from locking up during hard braking?
- A.
Brake caliper
- B.
Rotor
- C.
Brake lines
- D.
Anti-lock brake system (ABS)
Correct Answer
D. Anti-lock brake system (ABS)Explanation
The ABS modulates brake pressure to prevent wheel lockup, improving steering control and stopping distance.Rate this question:
-
- 7.
What can cause brake fade?
- A.
Overheating of brake fluid
- B.
Excessive brake fluid level
- C.
Worn-out tires
- D.
Loose wheel bolts
Correct Answer
A. Overheating of brake fluidExplanation
Brake fade occurs when brake fluid overheats, leading to reduced braking efficiency and increased stopping distances.Rate this question:
-
- 8.
What is the purpose of machining brake rotors?
- A.
Increase rotor weight
- B.
Improve brake pedal feel
- C.
Add decorative patterns
- D.
Restore parallelism and surface finish
Correct Answer
D. Restore parallelism and surface finishExplanation
Machining rotors removes imperfections, restores a smooth surface, and ensures parallelism, reducing brake noise and vibration.Rate this question:
-
- 9.
What does the brake warning light on the dashboard indicate?
- A.
Low engine oil level
- B.
Overheating engine
- C.
Low tire pressure
- D.
Brake system issues
Correct Answer
D. Brake system issuesExplanation
The brake warning light indicates a potential issue with the brake system, such as low fluid level or brake pad wear.Rate this question:
-
- 10.
Which component converts kinetic energy into heat to slow down the vehicle?
- A.
Brake pedal
- B.
Brake booster
- C.
Brake rotor
- D.
Brake caliper
Correct Answer
C. Brake rotorExplanation
The brake rotor, when clamped by the brake pads, generates friction that converts kinetic energy into heat, slowing down the vehicle.Rate this question:
