I have a question about front brake pressure. I recently purchased a SSBC pressure gauge to test my system and found only 700 psi at the caliper on both sides. I just put a new MC (15/16) from DoctorDiff. I think I should have more, like 1000-1200. I think this would solve my brake issue of never being able to lock the front brakes up. Could the rubber flex hoses be bad? I have an adj prop valve on the rear line. I still have the original combination block from the drum to drum setup. The calipers are 73 b-body stock discs. thanks for any help.
