- A.
One or two pistons
- B.
Spring and expander set
- C.
Both A and B
- D.
None of the above

Wheel cylinders typically contain both one or two pistons and a spring and expander set. The pistons are responsible for applying hydraulic pressure to the brake shoes, which then press against the brake drum to slow down or stop the wheel. The spring and expander set help to retract the brake shoes when the brake pedal is released, allowing the wheel to rotate freely. Therefore, both options A and B are correct.Rate this question:

None of the above
Correct Answer
C. Both A and BExplanation
The brake switch is responsible for sending an electronic signal to both the brake lights and the electronic brake control module. This signal is crucial for activating the brake lights when the brake pedal is pressed, and also for providing input to the electronic brake control module to assist with braking functions such as anti-lock braking system (ABS) and traction control. Therefore, the correct answer is Both A and B.Rate this question:

Which of the following typically reports the vehicle's speed to the electronic brake control module?
- A.
Wheel speed sensor
- B.
Vehicle speed sensor
- C.
Both A and B
- D.
None of the above
Correct Answer
C. Both A and BExplanation
Both the wheel speed sensor and the vehicle speed sensor typically report the vehicle's speed to the electronic brake control module. The wheel speed sensor measures the speed of each individual wheel, while the vehicle speed sensor measures the overall speed of the vehicle. By receiving information from both sensors, the electronic brake control module can accurately control the braking system based on the vehicle's speed.Rate this question:
-
- 48.
True or False. Some anti-lock braking systems require a scan tool that connects to the electronic brake control module or power train control module to read the fault codes.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Some anti-lock braking systems do require a scan tool that connects to the electronic brake control module or power train control module to read the fault codes. This is because the fault codes are stored in the module's memory and can only be accessed and interpreted using a scan tool. The scan tool helps in diagnosing and troubleshooting any issues with the anti-lock braking system by retrieving and analyzing the fault codes.Rate this question:
-

Which of the following is a typical sensor used by the electronic stability control system?
- A.
Yaw sensor
- B.
Steering angle sensor
- C.
Roll-rate sensor
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
The correct answer is "All of the above." This means that all three sensors mentioned - the yaw sensor, steering angle sensor, and roll-rate sensor - are typical sensors used by the electronic stability control system. These sensors are essential in providing data and feedback to the system, allowing it to monitor and adjust the vehicle's stability and traction in various driving conditions.Rate this question:
-
- 50.
True or False. Some traction control systems can be temporarily deactivated by a traction control system function switch located on the dash or center console.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Some traction control systems have a function switch that allows the driver to temporarily deactivate the system. This switch is typically located on the dashboard or center console of the vehicle. By deactivating the traction control system, the driver can have more control over the vehicle's acceleration and tire spin, which can be useful in certain situations such as off-road driving or when stuck in snow or mud.Rate this question:
