What is an ABS on a jeep wrangler

ABS means Anti Blocking System . It is a device that will improve your braking, especially during sustained braking. Before the development of ABS, the brake pedal was directly linked to the pads. When the pedal was depressed, the pads closed on the discs. The inconvenience with this mechanism is that there can be a risk of slippage. Using sensors, ABS calculated braking. Instead of pressing on the discs, the pressure will oscillate several times per second, which avoids a blocking complete wheels of your jeep wrangler. Not a single skid, and braking is more effective.
