Adjustable proportioning valve mounting location

If you want to save yourself the trouble of cutting and flaring brake lines, you can mount it parallel to the distribution block (side by side). You run the rear brake line into the PV instead of into the dist. block, then get a short length of pre-made brake line from the parts store (15-20" or so) and bend it into a loop, connecting the PV to the dist. block opening that is only about 1" away. A small angle bracket tucked under the disc. block screw will give you something to attach it to. It is still reachable from above, just a few inches lower than the position shown in #4.
