Are your rear drums adjusted properly that they were working before the HB install?
How old are the brake lines? Could one of the hoses collapsed causing fluid blockage?
I would also highly recommend a 1 1/8" master cylinder bore. I'm running an HB off a 05 tahoe w/ 1980 corvette master cylinder, it's been working great.
Did you block off the distribution valve when you were bleeding the brakes?
Did you check the master cylinder's pin clearance to be sure the HB unit would engage properly?*Jeff*

I was running standard brakes before, and all was working fine.
the rear drums are adjusted properly.
the rubber lines are a few years old and the only parts I did not replace on the brake system. I suppose that could be the issue?
i am running a new wilwood adjustable dist valve.
i was thinking that the hb unit is not engaging the MC properly. I will
measure that when I blow it apart and compare to the new MC.
