Thanks! I know that feeling all too well. I hate being away from the car when I would actually LIKE to work on it.






This is the stuff that gets me going!

So I have spent these past few days contemplating how I want to modify my braking system. Specifically the lines.

The goal: Remove the OEM proportioning valve and plumb in an adjustable somewhere in the cockpit, with ease of use, troubleshooting and maintenance in mind. The new valve will go in the REAR brake line.

After a few failed ideas, I think I have come up with a real winner.

So here's what I plan to do...


I removed the stock proportioning valve, which was mounted on the firewall at around the 7 o'clock position to the brake vacuum booster.






I then fit the OEM lines together with brake line flared unions (Factory fittings are M10x1.00 - inverted flare)

Perspective



Also...dropped my transmission out. Lots of room to work. The car hasn't been this stripped of drivetrain since the assembly line (1/73)







Where I have planned to install the proportioning valve is the type of stuff that makes me, a 25 year old dude, giggle.



This is my center console.

As you can kind of see, it's pretty decent. (would make a good plug for molding someday)

However I'm left with these unsightly holes to deal with.






So I'm going to turn a negative into a positive. I intend on hiding the proportioning valve (body) here, while trimming the center console (in said offending area) to allow the top of the valve to poke up through the console.



Locating it between the ashtray (which would remain functioning, for spare change/toll purposes) and the shifter.

The hole will be large enough to allow the console to remain easily removable, and would give it a really clean look. If necessary I can make a trim ring out of carbon, or glass, to really finish up the opening, as well.

Yay! for thinking it over!



I have to run into town later this afternoon to run some errands, but upon my return I will tear right into the install. I'm hoping to have it at least mocked up tonight.

Wish me luck.









Oh yeah, I changed the leaky pan gasket as well...But no one cares about that.

Okay.

Instead of using a bunch of unions, I just decided to remake the rear portion of the line.

I have made it to the proportioning valve. I really like the placement. I'm still far from done, but I'm off to a good start.





Here are some pictures to make sense of what I did. A little explanation too..





Cut the OEM piece at the approximate place for the the proportioning valve. The ashtray. And removed it from the car.




I then used that as a template and made my own line. With appropriate changes.

Flared with fresh M10x1.00 fittings.

So far so good. But so much more to do as well.

Stay tuned.

Finished the majority of the new line plumbing.

Rears are just about there. Fitment just needs a little bit of tweaking.



Also I trimmed the console.

Very pleased with how it came out. Very clean.

Haha! Almost doesn't need some finish attention. Almost.




My face is covered in dirt. Time for a shower.

Proportioning valve is roughly finished. Hooray!

Vtak control valve?

Yes.
