Hey All,

Just finished converting front drums to disc on my 64 C10. I bought the kit from Early Classics. All hooked up and lines bleed. I ran vacuum to an inlet on the manifold that is behind the carb (mid 80's 350). Started up fine, but brake pedal went right to the floor. When I turn the engine off there seems to be a bit more pressure in the pedal, but still goes right to the floor.

I read in the booster instructions that you are supposed to drill a hole 1" below original hole in the brake pedal. I didn't do this because the connecting rod coming out the back of booster aligned with the hole almost perfectly right out of the box. Booster diaphragm seems OK as I sucked on the vacuum hose and am getting no air through.

Please let me know what I am doing wrong. Is it a vacuum issue or is it the hole/angle off the pedal.

Thanks!

Dan
