Today I just replaced my drum proportioning valve with the one for rear disk. There is a "F" stamped on the base of them leading me to believe that they are attached to the front lines. Does anybody know if this is correct? I have already gravity bleed the fronts and if I don't need to bleed the rears I don't want to waste mine time doing so.
Thanks,
Patrick

yep, F for front R for rear

If the fluid is more than a couple years old, then it always good to flush new stuff through it anyways

This is the second flush in a year so I'm all good. I followed the lines and apparently the lines that attach to the prop. valves go to the rear.
