This is where the ABS bleeding scan tool comes into the picture. However, this sensor can make the bleeding process more complicated than it should be. This sensor detects wheel slippage and alters braking pressure, accordingly, resulting in the anti-lock effect. This is mainly due to the sensor present between the master cylinder and the calipers. However, there is a trickier bleeding process involved compared to non-ABS systems is more complicated. Given the more sensitive nature of anti-lock brakes, bleeding becomes a more crucial part in maintaining them. Worse, when such gradient imbalances are not checked, the brake pump and valves can potentially get damaged. With excess air (or contamination in the fluid lines) come alterations in the pressure gradient, which causes you to put more effort into pressing the brakes. It may not seem like much during most common driving conditions, but this can be potentially dangerous if not checked properly.įlushing that excess air out of your hydraulic brake lines is essential to get your brakes performing as it should. This is one of the most common reasons why you might not be getting the right amount of braking power, even if all your braking components are in top condition. The more air present in the lines, the more pronounced this spongy effect becomes, and the more effort you exert in bringing your car to a stop. When there is air in the lines, you make more effort on the pedals to channel out the desired braking force. The most common of air in ABS module symptoms is when the pedal feels spongy when you press it. This is most commonly done after having parts of your braking system replaced. As such, it is important that you bleed your brakes every now and then.

Even a bit of air inside the lines can make the entire system fail and result in subpar braking performance. When there's air in the lines, the hydraulic system that applies the brakes won't operate properly, resulting in brakes that don't have enough bite. For starters, having air in the brakes is something that you don't want to happen.
