<VV> flushing out brake lines for DOT 5

I always thought one of the main reasons I got married was to have someone
to help me bleed brakes.

I have since bought a Mity-Vac hand held vacuum pump and bleeding brakes is
MUCH easier than having a helper.

Not spilling a drop of fluid on freshly painted suspension pieces is a plus.

Not having to yell "PUMP IT" and hearing the response "DID YOU SAY LET OFF?"
is a plus.

Christine taking the same time to fix supper instead of helping me bleed
brakes...priceless!
