I'm prepping to install a set of Hedman headers in my '72 CS convertible with a 455. Per all the research I did on the forum I realize I will need to relocate the brake proportioning valve from the side to the top of the frame rail. What I can't seem to find are any discussions on how to do this. For those of you who have needed to move yours, would you share how you accomplished it? Thanks

 

Remove the bolt that attaches the bracket to the frame, then carefully relocate the valve to the top of the frame.
There is no need to remove any of the brake lines.
There is plenty of room in the brake lines to relocate the valve with no damage or kinking

 

Grab them firmly, with your two hands, and carefully bend them.

You got this.

 

Well that sounds a lot easier than I was thinking! I figured new brake lines, flaring, leaks, stripping flare nuts and bloody knuckles were involved. I really dislike brake line work.......!

 

Good info here, glad to know breaking the lines from the prop valve is not required (or changing any lengths, just mild changes in bends) as I recently installed all new lines.

 

How is the valve fastened in the new location? Just drilling a new hole out?

 

I think thats what I did, drill and tap a new mounting hole

 

On my 67 I didn't drill a new hole, I just moved it out of the way.

 

On my car, I used one of the factory holes for the clutch pivot. Since my car is an automatic, that hole was unused. Obviously not an option for manual transmission cars.
