• Brake system diagnosis and troubleshooting
• Brake adjustment and maintenance
• Safety and inspection procedures
1. What is the main function of the brake master cylinder?
A) Convert hydraulic pressure into mechanical force
B) Store brake fluid
C) Generate hydraulic pressure for the brake system
D) Operate the parking brake
The master cylinder pressurizes brake fluid to activate the wheel brakes.
2. Which component prevents fluid from flowing backward in a brake system?
A) Brake booster
B) Wheel cylinder
C) Check valve
D) Proportioning valve
Check valves maintain one-way fluid flow and proper brake operation.
,3. A spongy brake pedal is most commonly caused by:
A) Worn brake pads
B) Faulty master cylinder
C) Air in the brake lines
D) Dragging brake shoes
Air compresses in the hydraulic system, causing a soft pedal feel.
4. What is the purpose of a brake proportioning valve?
A) Prevent wheel lockup
B) Increase braking force to the front wheels
C) Limit rear brake pressure during heavy braking
D) Operate the ABS system
It prevents rear wheel lockup by adjusting hydraulic pressure.
5. Which of the following is true about disc brakes?
A) Less effective than drum brakes in wet conditions
B) Provide better heat dissipation than drum brakes
C) Cannot be used on front wheels
D) Require no brake fluid
Disc brakes stay cooler, reducing fade and improving stopping power.
6. When inspecting drum brakes, a groove in the drum indicates:
A) Normal wear
B) Excessive wear or foreign material damage
C) Proper adjustment
D) Low brake fluid
Grooves or scoring reduce braking efficiency and require resurfacing or
replacement.
7. Brake fade is caused primarily by:
A) Low brake fluid
B) Overheating of brake components
C) Worn master cylinder
D) Parking brake engagement
Excessive heat reduces friction between brake surfaces, causing fade.
, 8. Which brake fluid type is recommended for most vehicles?
A) DOT 3
B) DOT 4
C) DOT 5
D) DOT 3 or DOT 4 (hydraulic brake systems)
DOT 3/4 are glycol-based and compatible with most passenger vehicles.
9. How should you measure brake rotor thickness?
A) With a ruler
B) With a micrometer at multiple points
C) By visual inspection
D) With a caliper gauge only at one point
Rotors must be measured precisely to ensure even thickness and safety.
10.What is the purpose of a parking brake?
A) Stop the vehicle while moving
B) Hold the vehicle stationary when parked
C) Apply extra braking during emergencies
D) Operate the ABS system
The parking brake mechanically locks the wheels to prevent movement.
11.What does ABS stand for?
A) Automatic Brake System
B) Auxiliary Brake Safety
C) Anti-lock Braking System
D) Air Brake Sensor
ABS prevents wheel lockup during hard braking to maintain steering control.
12.Excessive brake pedal travel usually indicates:
A) Worn tires
B) Brake fluid leak or worn components
C) Dragging brakes
D) Low ABS pressure
Long pedal travel often means fluid is escaping somewhere or pads/shoes
are worn.
