The guy who installed my front disks, rebuilt my rear brakes and installed the power booster did something I find odd.
He plumbed the front disks off the single line that CPP marks as LEFT (on the proportioning valve) and the drums off the line marked RIGHT and capped the 1/4" outlet marked REAR. This seems totally wrong because all the lines are 3/16" and two rear 3/16" brake lines are being fed off of a single 3/16" line from the PV as opposed to the two rear 3/16 lines being fed from a 1/4" line.
I would think that a 1/4" line should be run from the PV to a "T" which branches off to two 3/16" lines, one for each rear drum, but not being a mechanic I don't know for sure.
For those of you who have actually installed this set-up how did you plumb your system?
BTW, when I was driving the truck I did not notice anything unusual about how the brakes worked.
