I installed a 6874BB2-11 Brake Booster Kit in my 1974 Nova and the brake are being applied without touching the pedal. I tried adjusting the clevis pin adjuster numerous times. But the threaded rod that came with the unit is too long and interferes with the brake pedal. After much frustration I measure the length of the rod from the old, original unit that came from the factory and it was much shorter. So I cut about 1/2" off of the rod of the new unit and it seems to be somewhat better.

But nowhere in the instructions did it measure to do this. This was definitely not an issue of having to drill a new hole as there was not way the clevis pin would have been in the center of the brake pedal area. But I have no other choice as there was no other way to eliminate the brake from being pre-loaded or applied constantly.

Has anyone else had this issue?
