So I bought a really nice used booster and master cylinder from a board member. It came with the prop. Valve that mounts up high near the master cylinder. I don't like the way that looks, would prefer to have it mounted down on the frame in the original location. Any reason why these kits mount it near the master cylinder? Any reason why it couldn't be down on the frame? And do you think the in line tube brake line "kits" with pre bent lines would connect to it if it was mounted on the frame? Not sure if the line input/output locations are in the same spot and would line up?thanks
Get what's called a "Hold off valve". Mounts in the same spot as the front-rear splitter. Now all you have to do is plumb it up. Tom T.
Thanks. After a quick Google search, what I have is a PV2 universal-combination valve. You probabaly knew that. Does that mean I still need a hold-off valve? And what is the purpose? Thanks
67's-70's use a hold-off valve to reduce and delay pressure to the rear brakes. 71 later it is built into the combination valve.
Ok, I think I get it now.. I haven't had a 70 before. So on a 70, I would need a hold off valve and a distribution block as in the 1st 2 pictures if I wanted a factory type set up. Or I could use what I have (the PV2) proportioning valve that does both. Anything else needed? Thanks
That's what is known as a "combination valve" because it combines the functions of the hold off valve and the splitter block found on 70 cars.. the factory went to that type of deal with a similar looking valve in 71. That setup you go from inline is great for guys with hot rods, with headers that either hit the factory valve when it's on the frame, and/or really make header install a pain. Inline should sell the bracket to put it on the frame, as well as the correct lines to plumb it down there, of you don't have headers, and want the original look. JW
Thanks. I changed my inline Tube order per their recommendation to the GM a-body lines that should go up to the PV2 at the master cylinder so shouldn't have to make any I hope.
