I have a 97 blazer, I just put in some new pads after that I bleed the brakes. I started from passanger back then drive back then passanger front then driver front. I also adjusted the drums. The problem is that when the car is off the pedal is hard ans sturdy but when I turn it on the pedal goes soft and when I press on it, it goes to the floor. When I drive it I can't brake as good as I used too. I have been pointed towards a bad brake booster but im not sure. If anyone could help me I would appreciated.
