Issues with Baer brakes

[Van B]

I ran a track event at Road America yesterday and had an issue with the brake system. I have bled the system to death and still can't seem to get it to work right. The only way to get good pedal feel is to pump the pedal once or twice. When I try to bleed them, no more air comes out.

The system: Baer supplied cast master cylinder (manual) which is supposed to be 15/16 bore. I am not sure of the diameter of the stainless lines I had a local shop make. 6 piston front calipers and single piston pbr calipers on the rear.

I had a line loc on the car when I had the lines bent and at the time wanted to keep it. The fab guy had the idea to use the line loc solenoid as a tee between the front brakes. Could this be my issue? I have no brake fluid leakage and yes, I attached the pushrod to the recommended hole in the pedal.

Any ideas?
