Brake Booster Losing Pressure with Engine Running

I also added a vac resivor, make the whole system a lot better

I've dealt with a disc brake conversion on my Jeep and I have to say, the conversion to this Bronco has been a bit disappointing. The brakes to me just don't seem to be fully biting or engaging to where I'm comfortable sending the wife or kids out on their own in traffic or high speeds on the road. Something still feels off to me, but I can't pin it down.

I think my real issue is related to vacuum at low idle and was hoping the reservoir would solve that. I've heard of electric vacuum booster type set ups, but have not read the need for them anywhere on a stock 302. Like stated, something is still off here.

Considering ditching this vacuum system and just making the jump to hydro assist.

I think you may of used the term "high speed" when referring to an early Bronco. Interesting concept
