Chassis systems Quiz

Which of the following is a feature that helps prevent wheel lock-up during braking?

• Electronic handbrake

• Hill start assist

• Anti-lock braking (ABS)

• Lane Departure warning (LDW)

Answer explanation

Anti-lock braking (ABS) prevents wheel lock-up during braking by modulating brake pressure, allowing the wheels to continue rotating and maintain traction, which enhances vehicle control and safety.

What is the primary purpose of an Electronic handbrake?

• To assist in hill starts

• To automatically apply brakes in emergencies

• To replace the traditional handbrake lever

• To enhance steering control

Answer explanation

The primary purpose of an Electronic handbrake is to replace the traditional handbrake lever, providing a more modern and space-efficient solution for securing the vehicle when parked.
