On;y way to be absolutey certain it IS NOT air in the lines is to
bleed your brakes again - and this time do it yourself so you can see
the fluid coming out, or have it doen and stand there and watch. I get a
helper to man the brakes and pur brake fouid in the tank - and I get
underneath with a wrench, a piece of clear plastic tubing and clear soft
drink bottle. I put the clear tube on the bleeder, turn it, have my
helper pump the brakes, and watch the fluid flow into the bottle until
the fluid runs clear in the tube, then I close it off. I have my helper
top off the tank, and I move to the next one. This is not a hard task,
but to be certain that your bleed job is correct - you must do it yourself.
If after all this, you still have problems, then start looking at the
brake master or even the brake booster. I don't know how you would test
the booster, but an internal failure in the master will allow you to
have a good pedal one moment then suddenly go down. If it does that -
relace the brake master cylinder.
