In current times, a stand-alone braking system is simply not enough. For safety of the driver and passengers, there are other systems that need to be in place to making braking safer. Case in point are anti-lock brakes; something that started out as optional and soon become convention for cars in most countries. Lets understand why.
A basic hydraulic braking system will only ensure that the inhibitive force applied by the brake pads on the discs is distributed evenly. Beyond that, it is really up to the driver’s skill and understanding of when to apply the brakes and at what intensity.
When a car is moving on uneven ground; incline, decline or turning tracks, the speed on the individual wheels may not be the same. Braking hard can induce locking of one or more wheels, which in turn can lead to situations where the driver loses control of the vehicle.
In that respect, anti-braking system have an integrated sensor system that keeps track of the speed or tractive force on each wheel. In the event that a wheel exhibits more or less speed than the other wheels, then the ABS kicks in and manipulates the braking force being applied to that particular wheel.
Depending on the technology, ABS can tinker with the braking pressure on the car’s wheels with varying frequency. Nevertheless, its not uncommon to see modern ABS monitor and adjust breaking pressure up to 15-times in a second, just so that the vehicle always maintains proper speed and control.
In other cases, ABS may decrease the braking distance through this process of automatic monitoring and situational application in a vehicle. The result is that the vehicle comes to a stop safely. Thus, the requirement of anti-braking not only augments the resident braking system, but it also reduces the chances of human indecision with regards to braking.
