Just finished a complete front end rebuild and conversion to disc up from with drum in rear on the 70. Bleeding the rear brakes I'm not getting anything out of the passenger rear and just a little out of the driver rear(a trickle not a squirt). I've got the proportioning valve installed correctly. The fronts bled fine. Have I missed doing something in the bleeding process? Ideas?

The proportioning valve came with the disc set up I bought used.

TIA Pete
