Brake pedal goes to floor with engine running

DON'T pump the brakes with the top/caps off the M/C,, as it may spray brake fluid/(paint remover) all over your engine compartment and perhaps fender and cowl.. !!

If you do accidentally get br. fluid on paint,, rinse IMMEDIATELY with water,,

Ask me how I know first hand... lol .. and had a few apprentices too...

hope it helps..
