Q: Loss of brake power/pressure once ABS is activated

Whenever the ABS get activated / hitting a large pot hole, I lose brake pressure/power and the pedal sinks to the floor before having any stopping power. On dry road, the brakes works perfectly fine and would not know there was a issue. The problem only occurs once the ABS is activated.

I once slowed down and let go of the brakes right before I hit a large pot hole and I still lost the brake power as described above. On a wet/snowy road once the ABS activated.. the ABS did it's job and when I hit the brakes soon after that, I experienced the same issues.

I need to turn off the car and restart it, then pump the brakes for them to get their pressure/power back. Once this is done, the brakes are "normal" again. If I pump the brakes after the ABS is activated, I do not get the brake power back unless I restart the car and pump the brakes with it in park.

I do not have any lights showing once the car is started "check engine/abs/ect..
