Ok digging up an oldie here but just gettin around to this.

I am try to start at the top with troubleshooting before I put in a generic disk/drum hold off/prop valve and a residual pressure valve in the rear circuit.

I have the master cyl no lines attached but with both ports plugged. The pedal is pretty firm right after the pedal free play is used up. BUT if I push hard enough the pedal seems to sink a bit - I then stop pushing cause I don't wanna bust anything.

Is this normal? Do I need to bleed the master further or is it just a bad master?

Doh - looked hard again and it seems that one of the plugs in the front port was leaking a bit sinking the pedal. Once I gave the fitting a good tightening leak stopped and the pedal held high and hard.

Will get valve mounted and plumbed next and move on from there.

Thanks
