Plumbing a adj proportioning valve?

65s said

I put KH discs on my '65 S and plumbed a Mopar Performance/Wilwood adj. proportioning valve into the rear line, right under the driver seat. Not inside the passenger compartment, but outside under the floor. It seemed like a nice place to put it, easy place to cut the rear brake line and the floor pan offered a nice hump where the knob hangs over so you can turn it. I had to drill two small holes in the floor pan for this though.

Now I can just stop the car, open the door, reach under and make an adjustment, then close the door and go again.

We did the same thing on my dad's chevelle. Super easy just spliced it into the rear brake line. There was already a hole in the frame/rocker where we wanted to put the valve under the door.

On my 66 it originally came with a single master and distr block. On my conversion I am using the original block and plumbing a new separate brake line from the rear master cylinder port to the adj valve to the rear wheels. This allows me to keep my original dist block and not have to spent $40 on a newer style duel master cylinder dist block. Not really an issue for you Goody, but for those of us with early mopars that came with single master cylinders this is the easiest way to go.
