Brakes seem to work fine now but when I have no pressure on the brake pedal I hear what sounds like a vacuum leak from inside firewall around brake booster. If I just lightly touch the pedal the noise goes away. I havn't put the brake light switch back under there. Would mounting that so there's a lil pressure on the pedal be the answer? Don't see any leaks around vacuum line on front of booster. Disc on front drums on back. First time on forum and beginner hot rodder.im 60'years old and was into in the 60s but forgot most of it now.
Uh, help me understand...

Tilt wheel, power brakes, etc were all factory available on the 76 full size trucks. Why are you having to cut and weld anything? This should be a total bolt-in.
