Which of the following do the dust shields help control in a disc brake system?
- A.
Dust
- B.
Water
- C.
Road debris
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
The dust shields in a disc brake system help control dust, water, and road debris. Dust shields are designed to prevent these elements from entering the brake system and causing damage or reducing the braking efficiency. Dust can accumulate on the brake pads and discs, affecting their performance. Water can cause corrosion and reduce braking power. Road debris, such as rocks or gravel, can get lodged between the brake pads and discs, leading to uneven wear and decreased braking effectiveness. Therefore, the dust shields play a crucial role in controlling all of these factors to maintain optimal brake performance.Rate this question:

Tech A says that when the brake pedal is depressed, a push rod creates the hydraulic pressure in the disc brake system. Tech B says that when the brake pedal is depressed, a push rod transfers the force through a brake booster to a hydraulic master cylinder. Who is correct?
- A.
Tech A
- B.
Tech B
- C.
Both Techs A and B
- D.
Neither Tech A nor B
Correct Answer
B. Tech BExplanation
Tech B is correct. When the brake pedal is depressed, a push rod transfers the force through a brake booster to a hydraulic master cylinder. This hydraulic master cylinder then creates the hydraulic pressure in the disc brake system. Tech A's statement is incorrect as the push rod does not directly create the hydraulic pressure in the disc brake system.Rate this question:

Tech A says that in disc brake calipers, the piston is sealed by a stationary round section sealing ring, also called a round cut O-ring. Tech B says that in disc brake calipers, the piston is sealed by a stationary square section sealing ring, also called a square cut O-ring. Who is correct?
- A.
Tech A
- B.
Tech B
- C.
Both Techs A and B
- D.
Neither Tech A nor B
Correct Answer
B. Tech BExplanation
Tech B is correct. In disc brake calipers, the piston is sealed by a stationary square section sealing ring, also called a square cut O-ring. Tech A's statement is incorrect as the sealing ring used in disc brake calipers is not round, but square in shape. Therefore, only Tech B's statement is accurate.Rate this question:

Tech A says that manufacturers have dealt with caliper brake piston corrosion by making pistons out of a phenolic resin. Tech B says that even though the phenolic pistons themselves do not corrode, the cast-iron bore of the caliper does corrode and rust and can therefore cause a phenolic piston to seize in the bore. Who is correct?
- A.
Tech A
- B.
Tech B
- C.
Both Techs A and B
- D.
Neither Tech A nor B
Correct Answer
C. Both Techs A and BExplanation
Both Techs A and B are correct. Tech A is correct in stating that manufacturers have dealt with caliper brake piston corrosion by making pistons out of a phenolic resin. Tech B is correct in stating that while the phenolic pistons themselves do not corrode, the cast-iron bore of the caliper can corrode and rust, which can cause a phenolic piston to seize in the bore.Rate this question:

Compared to a standard caliper, retracting the caliper piston on an integrated parking brake system is different.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
In an integrated parking brake system, the caliper piston is retracted differently compared to a standard caliper. This means that the process of retracting the piston in an integrated parking brake system is not the same as in a standard caliper. Therefore, the statement "Compared to a standard caliper, retracting the caliper piston on an integrated parking brake system is different" is true.Rate this question:

Which can be the cause of brake pedal pulsation?
- A.
Warped rotors
- B.
Anti-lock braking system operation
- C.
Both A and B
- D.
None of the above
Correct Answer
C. Both A and BExplanation
Both A and B can be the cause of brake pedal pulsation. Warped rotors can cause the brake pedal to pulsate as the uneven surface of the rotor makes contact with the brake pads. This can result in a pulsating sensation in the brake pedal when braking. Additionally, the anti-lock braking system (ABS) operation can also cause the brake pedal to pulsate. The ABS is designed to prevent the wheels from locking up during braking, and if it is activated, it can cause the brake pedal to pulsate as it modulates the brake pressure to each wheel.Rate this question:

Pinching off the flexible brake hoses with the help of vice grip pliers is a very good and recommended method to close rubber brake lines.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Closing rubber brake lines by pinching off the flexible brake hoses with vice grip pliers is not a recommended method. This can cause damage to the brake system and compromise its functionality. It is important to use proper tools and techniques when working with brake lines to ensure safety and proper operation of the braking system.Rate this question:

If the ________________ anti-lock braking system warning lamp illuminates, it typically means the vehicle's power train control module has observed a fault in the anti-lock brake system and will need to be checked for diagnostic trouble codes.
- A.
Red
- B.
Blue
- C.
Yellow
- D.
None of the above
Correct Answer
C. YellowExplanation
If the yellow anti-lock braking system warning lamp illuminates, it typically means the vehicle's power train control module has observed a fault in the anti-lock brake system and will need to be checked for diagnostic trouble codes.Rate this question:

How can disc brake rotors that have holes or slots machined into their surface help?
- A.
Dissipate heat more quickly.
- B.
Remove water more quickly
- C.
Both A and B
- D.
None of the above
Correct Answer
C. Both A and BExplanation
Disc brake rotors with holes or slots machined into their surface can help dissipate heat more quickly and remove water more quickly. The holes or slots increase the surface area of the rotor, allowing for better heat dissipation. Additionally, they help to channel water away from the rotor, preventing it from interfering with the braking performance. Therefore, both options A and B are correct.Rate this question:

Tech A says that if the new brake pads are burnished, it will result in longer brake pad life. Tech B says the opposite. Who is correct?
- A.
Tech A
- B.
Tech B
- C.
Both Techs A and B
- D.
Neither Tech A nor B
Correct Answer
A. Tech AExplanation
Tech A is correct because burnishing the new brake pads helps to remove any glaze or residue on the surface, allowing for better contact between the brake pad and the rotor. This improves the braking performance and can result in longer brake pad life. Tech B, who says the opposite, is incorrect.Rate this question:

Tech A says that a wheel stud that shows signs of cross-threaded lug nuts should be rethreaded with a die and put back in service. Tech B says that a wheel stud that shows signs of cross-threaded lug nuts should be replaced. Who is correct?
- A.
Tech A
- B.
Tech B
- C.
Both Techs A and B
- D.
Neither Tech A nor B
Correct Answer
B. Tech BExplanation
Tech B is correct. When a wheel stud shows signs of cross-threaded lug nuts, it is important to replace the wheel stud rather than rethreading it with a die. Cross-threading can cause damage to the threads of the stud, making it unsafe to continue using. Replacing the wheel stud ensures that the lug nuts can be properly tightened and secured, maintaining the safety and integrity of the wheel assembly.Rate this question:

- A.
Tech A
- B.
Tech B
- C.
Both Techs A and B
- D.
Neither Tech A nor B
Correct Answer
C. Both Techs A and BExplanation
Both Techs A and B are correct. The piston on a brake caliper that integrates the parking brake does need to be screwed back in on the threaded shaft to retract it into the bore. Additionally, a special tool is required that mates to slots, grooves, or holes in the outer face of the caliper piston to properly retract it.Rate this question:

A typical disc rotor is
- A.
Hub-style
- B.
Hubless-style
- C.
Both A and B
- D.
None of the above
Correct Answer
C. Both A and BExplanation
A typical disc rotor can be either hub-style or hubless-style. Hub-style disc rotors have a central hub that connects the rotor to the wheel, while hubless-style disc rotors do not have a central hub and are directly attached to the wheel. Therefore, the correct answer is "Both A and B" as both hub-style and hubless-style disc rotors are commonly used.Rate this question:

- C.
Both A and B
- D.
None of the above
Correct Answer
C. Both A and BExplanation
The rotor is usually removed when it is under the specified minimum thickness. This can happen either before or after machining. Therefore, both options A and B are correct.Rate this question:
