Too much vacuum?????????

["Phil" <hilljack7@xxxxxxxxxxxxx>]

I'd readjust the brake shoes, they should just barely rub when you turn the
hub by hand.
I'd also rebleed the system, I bet you still have a bit of air in there, but
I think the main problem is the brake shoes need adjusted. It doesn't hurt
when the shoes rub a bit when cold, because the drum quickly warms up and
expands away from the shoes when in use. There should be a little resistance
when you spin the hub, not a lot, but some.
