AARRRAAAUUUGGGHHH!!
Everything is hooked up and working. It is only minimal improvement. I went straight from the vacuum/canister into the booster and the performance of the brakes dropped way off. The vacuum is pulling 20", but it must need more volume. So, I "Tee'd" back into the line. The first hit on the pedal is delivering more stopping. When I pump the pedal, it isn't as effective. Looking back, I have replaced everything except for the portioning valve and the booster. The PO indicated that the booster had been replaced. When I bought the truck, the breaks were really bad. One of these days...
