Brake dragging on passenger side,advice/help needed

This is on my 72 scamp manual brake/stock 73up disc conversion that has been on the car for a while,drag car and working fine.Had got a bit of pull in the pits so checked it out when we got home and found that the passenger side spinning the wheel didn't really spin,could move it put would stop when I let go,driver side was better tire would spin apprx a 1/4 rev after letting go.Cleaned and lubed slides re-assy and was a bit better,took it out and rechecked and was back like it was.So got a few weeks before the next race so i got new calipers and hoses and installed today figures i'd be good to go.After bleeding I can turn the drivers side with some effort but the pass is worse now then before.With the wheel off can barley move it with 2 hans on the studs,drivers side is a one hand deal.Do I have a bad new/rebuilt caliper,is it something with the bleeding?? If i crack the bleeder what should I get.When I took apart the pass side the brake fluid kept dripping out till I got the new hose in,had to keep the m/c filled up till I got it,the drivers side barley leaked at all and of course that hose went right in.Have good pedal but have not driven it at all yet.
Well that was long winded,just a bit baffled as the one side is holding and the other seems ok.

Thanks
