Ok, 1988 M35A2, dual brake system. First, Rebuild both air packs because i had brake fluid blowing out the vent tube. After rebuild, bleed brakes. When i bled rear brakes, pedal goes to the floor, when I bled the front brakes, pedal stops about 2" from floor. I'm doing the the 2 person method of bleeding. I'm Thinking, major/minor brake adjustment. Any other guidance?
