Hydro boost, rear lock up?

Just bought the 77 Scout with a 304 and manual, already had what looks like and astro van hydro boost set up in it. My problem is the rear brakes like to lock up with almost no pressure on the pedal, and I was wondering if there is a way to adjust the pressure going to the rears or if I just need to de-adjust the rear brakes? Oh yeah, monte the radiator worked like a charm!

Are the resevoirs the same size on the master cylinder? If they are, they are for a dual disc set up. If the master cylinder resevoirs are different sizes then you have one for a disc/drum set up. Also make sure the rear brake lines are plumbed into the smaller side resiovoir on the master cylinder. Mine just happens to be the front side of the master cylinder runs the rear brakes. It also has a larger brake line ussually. I just installed a hyrdroboost on my '69 800a.
 
The resevoirs are different sizes the smaller one being on the front, but I'll have to check the line routing to be sure it is set up right.

Thanks
