Question

What is Anti lock brake system?

Answer 1

An anti-lock braking system is a system on motor vehicles which prevents the wheels from locking while braking. The purpose of this is to allow the driver to maintain steering control under heavy braking and, in some situations, to shorten braking distances (by allowing the driver to hit the brake fully without skidding or loss of control). Disadvantages of the system include increased braking distances under certain conditions and the creation of a "false sense of security" among drivers who do not understand the operation and limitations of ABS.

Answer 2

The anti-lock computer picks up signals from wheel senors that tell it when a wheel is about to lock up and the computer will adjust the hyd pressure to that wheel and not allow it to lock and this give you a better and shorter braking distance and also more control. You see if you wheels lock up in a hard braking than you are not stopping as fast as you wheel when the wheels keep turning. When the wheel locks it has lost traction and no longer slowing you down.

Answer 3

Anti-lock brakes are designed to keep cars from going into a skid when the brakes are applied in an emergency.

Designed to allow the driver steering control, ABS brakes work by automatically actuating the brakes on and off during emergency stops.

They are effective in helping drivers avoid accidents. In certain situations, ABS brakes can help to shorten stopping distances.

Answer 4

It causes the wheels in the car to rapidly brake and release to avoid the wheels locking up, which would just cause the car to slide and not be able to steer. It's a nice thing for inexperienced drivers to have in poor weather, but just an annoyance for me.

Answer 6

Normally when you drive you apply brake slowly and the vehicle come to halt slowly. But in an emergency situation you slam the brakes. What happens then is that the rotation of the wheels stops due to braking.  Still the vehicle moves on due to inertia. The tyre marks you see in the roads is due to this. There are two disadvantages due to this.

Only one portion of the tyre is touching the roads and because of the friction the tyres might burst. But it is not common.

The biggest problem is, as the wheels are not moving you can not steer the vehicle.Whichever direction you turn the steering the vehicle keeps on moving in the same direction and hit the target you wanted to avoid. At any condition the steering is functioning correctly. But as the vehicle is not moving but sliding it does not respond to the steering. If there was little bit movement of the tyres you could control the vehicle using the steering.

Here the ABS becomes useful.It does not allow the wheels to brake completely. When the wheel movement is going to be stopped it releases the brake slightly. Because of this you can control the vehicle using the steering. it gives you steering control but the braking distance get increased.
