I have never touched my proportioning valve, I successfully bled after lines to the rear and wheel cylinders.

I just use my hand held vacuum pump. One man brake bleeding job. Just hook on to the bleeder valve at the cylinder or caliper and suck hard.lol I wouldnt touch the prop valve.

As the other guys said, you don't need to do anything with the proportioning valve. Brake bleeding is much easier with a buddy pumping the pedal while you're working the bleeder valve, in my opinion. Definitely not the only way to do it though.

I believe you're supposed to pull it out, but, as everyonre said, it does'nt seem to make any difference, and I never bother with it

It's been a while but we went over this and "Ford says" it needs to be
held-in for certain years and other years (models?) needs it held-out. :/

Ford huh? ;)

My '75 F150 and the Ford manuals I ordered to go with it sez: "hold it out"

So... I made a tool to hold it out! :) (1/32" thick spring tempered 1095)

Either it stopped me from bleeding the brakes or was of no use (can't
remember which) since doing nothing like Bgas said, works for me too.

Bleeding brakes is a one man operation if you...
put some clean brake fluid in a jar...
put a long thin hose on the bleeder...
open that bleeder just a little...
submerge the hose-end in the brake fluid in the jar...
slowly pump the brake pedal...
while watching the master cylinder under the open hood...
so it doesn't get too low on fluid. :)

My son Roger showed me that trick. :)

What do you think? :)
