Answers

1. b) The ABS, also known as an anti-lock braking system, prevents the wheels from locking during sudden braking, which allows you to maintain some control over the vehicle’s direction and reduces the risk of an accident. Since 2012, all new cars sold in Canada must have this system installed.
2. c) When firmly pressing the brake pedal, the ABS uses sensors to calculate the wheels’ speed. If it detects an imminent lock-up, it automatically pumps the brakes. During this manoeuvre, it often feels like the brake pedal is vibrating.
3. b) If you notice that the ABS warning light on your dashboard remains on, you should take your car to a repair shop for an inspection. It could be that the brake fluid level is low or a wheel speed sensor has been damaged.

Your car’s ABS must be serviced, just like the suspension, bodywork, and engine. Your mechanic has the necessary skills and tools to examine your braking system properly. Need to make an appointment? Contact your nearest M 360 mechanic today.
