So I bled my brakes today in the order of (lr rf lf rr absf absr) and there where no airbubbles what so ever in the lines or coming out of the calipers. Now i have a solid pedal with the car off but when i turn it on and the brake booster kicks in i can push the pedal almost all the way to the floor before the brakes are applied. Sound like there is still air in the lines or is there another issue?

Yup sure sounds like it. try bleeding them again and see what happens, If that fails then post back.

I have the same issue, check the clamps on the brake booster vacuum lines, if those are tight then test the line itself. The clamps on mine were loose enough to get off with fingers, normally you need pliers for em'. Does pedal pressure return after a long period of not using them? Or does it stay loose the entire time?
