yar, got to use a little common sense here. Believe me, I pump enough fluid to be way past the bubbles. Brake fluid is cheap compared to an accident.
ALSO.... once bled all you have to do is wait a little and it will tell you if you have a problem. Like, is the pedal still firm or does it go down?, does it "pump up" indicating still some air in the system? Lots of checks and balances you can notice before ever putting it on the road...which in my csse may be months and plenty of opportunity to evaluate. Like I said, good common sense if you know anything about mechanics.....if not then yes, leave it to the pros.
I might add that bench bleeding a m/c will take a lot of work out of bleeding a system.
