How do you install an adjustable proportioning valve?

Matthew,
Please keep us posted as you sort this out. I am changing out my front calipers and power slot rotors to 24mm. I already have ducting from the front bumper. I am leaving the rear brakes stock for now. Thanks, Craig

Hey guys, im making a bit of progress on the design but I have a quick question...

Any harm in using SS flexible brake line hoses for a 911 with adapters to and from the P/v and the hardline?

Bump for an answer.

Matt, why didn't you just buy a used Carrera p/v for $20? Are you building in flexibility for future upgrades?

No that would be fine, though the steel tube is easy enough to form as well, you just need a bender.

Bill, any trouble flairing the factory hard lines up a bit? Say at a 60 degree angle?

Well a couple of forseen reasons.

One, I like the idea of the adjustablity. Two, it didnt cost me much more for it (5 bucks). And three, my weight distribution is slightly off due to my weight reduction and the fact that I dont run a spare tire. Infact I recently locked up the system and it seemed to still lock up the fronts first. I think. haha. Well at least it didnt get unstable.

Does anyone know what size fittings mate with a SSI flex brake line for a '79 SC?
