Bleeding the brake system on the 68, as usual I was starting with the passenger rear. As soon as the front brakes (discs) got some pressure the brake fluid stopped flowing to the rear. I feel confident the pressure differential caused the valve to shut off the rears completely (actually a great safety feature).
My question is how to get around this wonderful feature so I can bleed the darn brakes. the manual was a little vague on this one.

At one of the local parts stores I purchased a vacum gage & pump that is good both for adjusting the idle screws on the carb and bleeding brake fluid into a little cup without having to pump the brakes. That has worked well for me in both respects.

Bleeding brakes

When this happens (the diff. valve pops to one side) you will get the effect you saw. The proper way to re-center the valve is to close all ports and pump the pedal -- a lot!.
