I just finished installing my rear disc brakes and am in the process of bleeding the system....BUT I'm still getting air in the lines when bleeding the FRONT brakes. The only change I made is the order the front line from the master cylinder goes into the combination valve...it used to go into the side of the combination valve but now its in the front. Does the order make a difference in the pressure the system receives? The back brake lines are fine...only having a problem with the front.

Its a new brass disc/disc valve (ditched the old drum combo valve and prop valve set up) from Classic Industries. I know its kind of hard to explain what I'm talking about..should have pics of it soon. Any help would be appreciated.
