ABS is a device which is used to assist braking (that means it only help in braking) its consists of solenoid valves , a few extra brake lines and sensors and its own brain (ECU) which is connected to the main ECU as well to receive some info from the EFI sensors and normal sensors ( like vehicle speed sensor )
Purpose :-
The main purpose of the ABS was to stop the locking of the tyres due to hard pressing the brake pedal in a emergency because locking up the tyres causes loss of traction in mid and high speeds when the car has momentum in it , this prevented the car to slid of when the brake pedal was pressed hard and provided good stability of the car but it eventually evolved and now a days the ABS system controls almost all the function of your braking even braking for u if your too busy flooring the gas pedal in a corner or in the streets
Now the ABS is paired with something called Traction control and VSC (Vehicle Stability Control) which control all the situations occurring in one's car which could cause loss of traction on the road or track (Tho some people tend to turn it off during a run on the track)
Working :-
The ABS works with the 4 ( 1 for each wheel ) or 8 ( 2 for each wheel ) solenoids given in the ABS unit which work by transferring the brake fluid from one line and give it to the next line thus assisting the braking to brake all for wheels at the same speed no matter what the condition( as if the vehicle is on the a watery surface) so the vehicles doesn't lose traction while braking . It got popular because it provided safety and also because it provided improved track timing for the new generation of racers
The Traction control and VSC work by using three more solenoids one to cut out the master cylinder during a hill climb turn and hard pressed turns when you can not let go of the accelerator . Then it uses the second and third solenoid to give stored pressurized brake fluid and give it to the ABS to work its magic with it like you r press the brakes at a professional level. It works at times like when one of your cars wheels is stuck in a ditch and the power is going to waste at the wheel which is above contact to create pushing force , at this time the Traction control lock the slipping wheel and the power moves to the wheel which has a contact with the ground thus your car runs out of the ditch . The VSC work on the roads or track where u cant press the brake because u will lose the power from the engine if u do that it automatically brakes and release the wheels to provide the best traction of the wheels with the ground so your car moves smoothly through the turn
Problems :-
The common problem with the ABS system is the relays which power up the ABS system and blown out fuses , on rare occasions the solenoids become weak or stop working or the rubber seal on them becomes weak , and on even more rare occasions the ECU gets fried but it has alot of fuses and breakers protecting it so it rarely happens
The ABS has a fail safe Function in it that means if there is something wrong with the System it will return to its original braking method
