Mazda_Powered so sexy!!! coming along great man! we'll be done around the same time i think haha.

Hopefully it will be done for the summer.

Turpro You're a beast
I know LOL

Had fun at the shop today. Read about a dude that used cloths line for templates for wiring and plumbing. Figured I would give it a try. I would do it again, it was really helpful. I used painters tape and cloths line to "plumb" the brakes. I labeled the lines and took them to the parts store. I laid all the cloths line on the floor and matched it up to real brake line. Three of the lines were metric on one side and standard on the other. The proportioning valve was standard and so was the brake line tee I bought. I bought all metric lines and cut and flared the standard fittings on one end of them. I made brackets for the adjustable proportioning valve and came up with a clever spot for it. It fit perfectly in one of the drain holes. (lucky)

Nice work jason. Only concern..kisking the proportioning valve with you foot.

[Mazda_Powered]

great idea! is it going to get in the way of anything?

[IMACHU2]

I have short legs, so it will be pretty close to the front of the seat. It is located in the same place as in the Mustang. I "test drove" it in my daily driver 323 It appears to be out of harms way. (duct taped it in the hole in the floor and drove around the block) LOL. The only problem now is I had to look under my daily driver 323 a few time to understand and see where potential spacial conflicts would be. It is really, really scary under there
(the carpet is a structural member).

Looks good and great job on the brake line plumbing.

I just read the entire work log, you're doing excellent job!

Just giving you a tip. You know the brake lines has to be "equal lenght" (front to front and rear to rear) or the pressure in the break lines are going to be un-balanced. The car will turn right or left depending in wich line is the shorter when breaking very hard. But since you installed an adjustable proportionning valve I guest you knew that.

Good luck!!

While its true that flow would decrease pressure available at various distances from the source for things like water systems..the "flow" in a brake system is nil so the distances, number of elbows etc have no effect...pressure will equalize throughout the system. The only thing will be extra fluid in the system to take up extra length. Pressure in the closed hydraulic system will remain equal at all times. Your input/output force ratios will change when your input/output piston diameters change. The lines connecting to the pistons do not affect pressure.

Theory behind a proportioning valve:
At lower pressures, the prop valve effectively does nothing. At higher pressures, a piston separates the fluid at the inlet and outlet sides. No fluid flows through the valve. Therefore, the pressure locked into the system will remain constant at the preset (factory prop) or adjusted rate (as in an adjustable prop). Keep in mind the proportioning valve can be used to reduce brake line pressure, but will not increase it.

doesn't matter on length like said above, thats why you always bleed the longest/furthest line from the master cylinder first.

[mazdasly75]

Well, the only thing I can tell you is to do a performance test. The calipers won't receive the same pressure at the end and it's cause of the different length of the brake line. I can't argue more as I'm out of words, I speak french so I'm missing words.

Anyway, it's a huge project that grown at an awesome speed. Keep the tempo dude!

Cheer

Argue with Pascal. LOL

Pascal's Law

Pascal's Law states that, because fluids are virtually non-compressible, any force applied to a closed hydraulic system will be felt equally and instantly throughout the entire system.

[Mazda_Powered]

Haha so true, french is completely different when trying to give an explanation. I'm average with my french skills, and I know literal translations don't mean crap, almost twice the syllables, and explaining the smallest thing usually twice as long haha.

this is coming along nicely. i hope to do something similar once im out of college and get another bg. I hope none of those rubber brake lines start to leak, you dont want all that nice paint work flaking off.

Thanks. They look like "rubber brake lines", but they were engineered to do what they are doing-carry brake fluid. (Wilwood remote brake reservoir hose). The fittings will hold up to 250 PSI and there is actually a slight vacuum on them, so the "nice paint work" will be very safe.
