When would an anti-lock braking system start to work?

A Just as the wheels are about to lock.

The anti-lock braking system has sensors that detect when the wheels are about to lock. It releases the brakes momentarily to allow the wheels to revolve and grip, then automatically reapplies them. This cycle is repeated several times a second to maximise braking performance.

An anti-lock braking system (ABS) is a safety feature that helps drivers maintain control of their vehicles in emergency situations. ABS works by automatically applying and releasing the brakes multiple times per second to help prevent wheel lockup, which can cause skidding or loss of vehicle control. The question then arises: when does an ABS start to work?

The answer depends on the type of system installed in your car and how it is set up by your mechanic. In general, most systems will begin working as soon as you apply pressure to the brake pedal with enough force for them to detect it. This could be just after pressing down lightly or may require more significant pressure before they activate - this varies from one model/make of car to another so make sure you check with your mechanic if unsure about yours!

Overall, having an anti-lock braking system installed in a vehicle provides added peace of mind when driving since it can offer extra protection against unexpected events like sudden stops or slippery roads where wheel lockup might otherwise occur without its assistance. It's important for all drivers who have such systems fitted into their cars (or are thinking about doing so) to understand exactly how they work and what scenarios they should expect them kicking into action!
