How do you bleed air from ABS module?
This is done by pumping the brake pedal firmly 40 times with the ignition off. After repairs have been made, the lines can be bled manually, with a conventional power bleeder, injector tool or vacuum bleeder. With all of these methods, leave the key off so the ABS pump does not pressurize the accumulator.
Do you have to bleed ABS module?
If you felt that the brake pedal is so spongy or soft, then this is the first sign that your ABS module and the whole braking system needs to be bled to get rid of the excess air that in the brake system. This may occur some problems to the ABS system or it may get weaker.
Why are my brakes soft after bleeding?
If air gets into the brake lines, it can prevent brake fluid from flowing properly, causing the brake pedal to feel spongy or soft.
