Most likely you will not need a manual proportioning valve if the whole 
rest of the brake system is stock, but you still gotta test the results before 
getting into traffic. Fooling with the brakes is much more serious that 
fooling with the engine because of the possibilities for running into someone. 
A very 'hard' pedal with little slowing can indeed be a sign of an inop 
power brake booster. But as I said, the real test is 0-1500 psi pressure gauges 
in both front & rear lines. These can be temporarily attached via the 
threaded bleed nipple holes on a front & rear caliper. Some big brake shops can 
do this or you can rig your own. Good luck- J Deryke
