Question: 1 / 400

A defect in which system can interfere with a vehicle's ability to slow down or stop?

Power steering system

Braking system

The braking system is essential for a vehicle's ability to slow down or stop effectively. It comprises various components such as brake pads, rotors, calipers, and fluids that work together to create the necessary friction to halt the vehicle safely. If there's any defect in this system, like worn-out brake pads or low brake fluid, it can lead to reduced braking power or complete brake failure.

This is critical for driver safety and controlling the vehicle, especially in emergency situations where immediate stopping may be required. Ensuring that the braking system is in good working order is a fundamental part of vehicle maintenance and driver training, emphasizing its importance on the road. Other systems like power steering, cooling, and transmission play roles in vehicle operation but do not directly affect the capacity to stop the vehicle.
