I did not read the front pressure because the fronts are solid and seem to
be working. Since I had the front working, no leaks, etc I did not want
to open that part of the system up. Not really sure why that would tell
me more? 800-900PSI at the MC and 300-400PSI at the caliper. Huge loss
somewhere in the rear system and the combination value seems likely. From
what I have read, the PV2 value will cut the pressure by 1/2 within a
certain range. I¹m thinking I got sold the PV2 instead of the PV4 when I
replaced it.
