Proportioning Valve?

Moving right along with the disk conversion & brake line replacement. The master cylinder to prop valve lines that came with the brake line kit, does not match up with the original Prop Valve I got from the donor. The lines fit without the mounting bracket. Is it necessary to have the prop valve mounted on a bracket?

Re: Proportioning Valve?

Wow Steve that looks good! I would use a bracket. Isn't there enough flex in the lines to make it work?. I had a heck of a time with mine also but I finally got it. Maybe you could fab up a trick bracket? That MC looks different than mine.

Re: Proportioning Valve?

Mine doesnt have a bracket. Not sayin you should use this POS as an example, though! By the way, I've got a new booster, MC, and prop valve on the way to get rid of this eyesore, so leave me alone!

That ms is brand new. Not rebuilt. $39 at Advance Auto.

Maybe I'll make some kinda bracket up. The brake line kit went in nice. No bending needed. I hope to have this job wrapped up by the weekend.

They look really nice! I see you already got the control arms back in too.

Re: Proportioning Valve?

Very nice and clean! I mounted my prop valve on a bracket, but with the rigidity of lines, I think you'll be fine??? maybe not...

Re: Proportioning Valve?

vibration and flex over time will cause the lines to crack and fail usually at a most inoportune time// save an oak tree some grief make a bracket

Re: Proportioning Valve?

I agree with cdowns.If you didn't need to mount it the factory would not have gone to the expense.

"save an oak tree some grief" What about a "Ficus"

Maybe I'll get a piece of "Maple" and make a bracket.

Kidding aside, maybe it would be best to make a bracket for it.......
