Sorry it has been awhile since I posted anything on this. I haven't had a lot of time to work on it lately due to work, however I got some things done yesterday and today and believe I got it sorted out. As I went through on here previously, I have replaced the 4 front wheel cylinders which did yield some positive results but there were still issues with the front brakes locking up. I then focused on the brake booster system. I ordered 1 new one which turned out to be the wrong type ($200 gone); I decided to disassemble and clean the booster which services the front brakes. I removed the booster and took it apart; it was pretty grungy with rust/dirt/brake fluid but nothing super bad. There is a valve in the front of the cylinder which seems like a residual pressure valve or something close; it has a rubber base, spring and cap all held in by a small wire snap ring. I disassembled it, cleaned and when I went to reassemble it the snap ring decided it was time to depart and shot off into the unknown. After an hour of looking I went to Napa and bought some normal snap rings (2 trips to get it right); but as they say persistence pays off and I got it all back together. When I had removed it, the feed line was leaking from the MC which I expected and caught with a pan. After I got the booster back together I reinstalled it. I then went to add some new brake fluid and bleed the booster; it was then I noticed that the booster I was working on was actually for the rear brakes...
ullinghair: so out came the "other" booster and got to practice my brake booster rebuilding skills. Got that one back together and reinstalled. I then bled them both and it was time for a test. Started the truck up (that 360 runs really well), put the truck into reverse, the truck moved and I hit the brakes, they grabbed as always (very grabby); release the pedal and VIOLA it moved. They did grab/lock once, but I moved forward and they released. I then took it down the road to see; that's when I found out that the very large hood was not latched.... I was going slow so I stopped and closed it. Continued down the road without issue, then turned around and came back w/o issue. Actually the brakes seemed to get better as I went. I still need to tighten the lug nuts and reinstall the gas tank support (bar that runs between the 2 tanks). So, for the most part I think I am past this (finally).
