I have newly installed corvette brakes with a master cylinder and prop valve. I have bleed the brakes twice now and the same thing has happened

1) bleed each brake (RR,LR,RF,LF) until no air comes out and the pedal feels stiff
2) start the car and the pedal goes soft (all the way to the floor)

Any ideas or do I just need to keep bleeding? So far air has shown up between the two bleeds I have done.


Thanks

No I never knew about this process until after my first bleed. I bled the master cylinder after the first before the second bleed

Get the back of the car as high as you can and bleed again. You want the master cyl tilted down, with it tilted up air is trapped.

I will try this when I get a chance thanks. Can anyone explain why the issue occurs when the motor runs?
