Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
I put a reply down below but just further to this, yea did the modification to the bolt head. But I didn’t get it completely flush. Sticks out about 2-3mm, you think this could be a problem. I currently have fluid coming through, but the spongy brake pedal is the problem here currently.did you do the booster rod bolt head/thread mod on the VS plastic booster???
Did you connect the front/rear lines in the appropriate ports on VT master???
No fluid in the rear points to block in line/issues with master piston/seals and booster problems which will be felt when pressing brake pedal.
Would the shoes need to be adjusted if they haven’t been touched? I only replaced the Fronts and didn’t do anything in the rear.The line out of the master closest to the booster is to the rears.
Why did you cut the valve?
Have you checked the brake line isn't clogged slightly?
The brake shoes...If they aren't adjusted correctly it will give you a low brake pedal feel....
If there is air in the line, pumping the brake pedal should cause it to come up higher...So another thing to consider
