  I have had to deal many systems with high points like you have 
mentioned and I have tried to bleed them out but they always develop 
an air pocket in that high point and the only way to stop it is to 
make that high point your pressure relief point.
  To do this I have  made a remote pressure relief cap assembly and 
tapped off that high point, note that the cap you now have on the 
fill point must be replaced with a with a non vent cap to seal it and 
force the venting to take place at the high point.
  In the case that there are two high points I bring a line from each 
point to the remote pressure cap.
