I have been beating my brains out on this, read the other posts about bleeding. Tried pressure bleeding from the wheel cylinder, from the master, Inching then brakes, brakes then inching. I have replaced all the components. What I don't understand is on the new selector valve there is a one way valve screwed on top of it. The direction of the valve is to open when there is pressure from the wheel cylinders but close when there is pressure from the selector valve. I triple checked the brake line routing to this, Brake MC on the end, tube to splitter to each wheel cylinder out the top, inching MC on the other end and tube out the top to the inching valve. i Pulled the check valve out, pressure bled from the MC and it comes out the selector valve at the check valve port, did the same with the inching. Put the check valve back in and have good pedal on both but no fluid going to the wheel cylinders. Then pressure bled from the wheel cylinders and now no brake pedal or brakes. I have done this 4 or 5 times thinking there still must be air in the system but same results.
