1968 rear brake 2 piece hold off valve
I am in the process of replacing the original 2 piece front disc rotors and calipers. I also replaced the hold-off valve since the lower bolt was slightly corroded. Four years ago, I installed a new master cylinder and power booster. When we started to bleed the rear, we could not get any fluid out. After trying for over an hour, we decided to try the front, and if successful, then go back to the rear.
We were able to get the front bled, but still no success on the rear. Next step is to go back and reinstall the old hold-off valve. I also thought to try disconnecting the rear brake line from the hold-off valve to see if fluid is getting through, but that is going to be a BIG mess and this is a concours car. Has anyone had a problem with a repro hold-off valve or an issue like this?
Thanks in advance.
