Try this,push right piston all the way in. C clamp so it stays in. Then push left piston in. Keep emptying master so it wont overflow. That should push any air out,like reverse bleeding.
Then re-install and pump em back up.
Something else,there may be a chance the piston seals could be sticking,and rolling over,then as they sit, the seals draw pistons away from rotors. Not likely with 3psi valves in the system.
And why does something so simple have to be so difficult??
When i did the chevy a couple weeks ago, 190 pumps to get fluid out of the bleeders.
