      I flushed the brakes in my 98' VW VR6 the other day and now have a soft pedal. I used a motive power brake bleeder, ATE TYP200, and I am almost certain all the air was removed or never introduced. The pedal is stiff when the ignition is off, however, once the car is running and brakes are utilized, the pedal is much softer (can almost easily be pressed to the floor, and braking performance is very poor).

      Any idea what is going on here, and where to possibly start troubleshooting?

      You need more fluid?? How's the level? Do you have a leak?

      No, the res. fluid is perfect and hasn't moved. No leaks as far as I can tell. I was thinking a rubber line is fatigued, but I did not have this problem prior. I bled every wheel thoroughly and in the proper order.

      There's air in it somewhere, or you have a leak.

      1st culprit: Air///// 2nd culprit: Leak. Almost certainly one of these 2. When putting in new pads, there is almost always a soft pedal to start (fluid needs to move) If bleeding/flushing, there has to be a shut off before the pedal rises or air will enter, often a pressurised method is used. I have always used the 2 person method and never had issues BUT... it can always happen. Bleed them all again. Hope we are helping you.
