Did you bench bleed your master cylinder?

If you did have you tried opening your bleed screws and let gravity kick in?

Sounds like you got air in your lines.

The prop valve shuttle valve may have moved, closing the front circuit. Is the brake light warning light on? Crack open a front and rear bleeder at the same time, bleed and then go back to normal bleeding procedure, that usually re-centers the shuttle valve.

no the brake light is not on. I did bench bleed the master cylinder. I will try do the open a front and rear bleeder to reset the valve. if I was to replace the valve should I get a stock one or a adjustable one
