What is ABS on a Toyota Rav 4 (4nd Generation)
ABS stands for Anti Blocking System . It is a system which will make it possible to perfect the braking system, among other things for continuous braking. Before the invention of ABS, the brake pedal was simply linked to the pads. As soon as you pressed, the pads stick to the discs. The trouble with this system is that there can be a risk of slippage. Using probes, ABS assesses the braking system. Instead of maintaining the discs, the pressure will decrease and then increase a number of times in a very short time, to prevent blocking overall tires of your Toyota Rav 4 (4th Generation). No skidding, and braking becomes more efficient.
