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...
If it will help you out you can have my old booster, I'll send it to you for shipping cost. Its an 11" and worked fine I wanted a smaller one to clear my valve covers on the BB. Let me know if you want it and well work out the details later
I know how frustrating this can be
