This does not seem normal and indicates to me that something is wrong with the master cylinders. Bob, are you sure it is air bubbles and not just a back flow of brake fluid when the brakes are released? If it is air, then it is a loose or leaky connection or a bad brake cylinder. That covers the entire system. Air in the system is cause for great concern on a IV-P. If the pedal goes away after take off then it could also be a warped rotor knocking the pads back. A low pedal during heavy braking could be water absorbed in the brake fluid. Changing out the fluid with new will fix that. I can't think of much more. Craig Berland
