Brake System light revisited

not yet... need a second person at the right time. I will give this a try and if it doesn't work go ahead and bleed the brakes again. Seems to me that it could be weak spring in the new unit, or something hanging up and holding the piston off center. I have the original distribution valve. Is there anybody here that can test/clean/refurbish it?

I take it if you can bleed the system without the piston being centered (post#22) then all the brakes work even if the piston is off center?

Do you have the ports plumbed correctly?
They are prebent lines and (thank God) really can only be installed one way.
