Brake proportioning valve and bleeding brakes

I'm trying to bleed my brakes and have not had 100% success yet, even when following the front-back-front procedure. I find that I can't fully depress the pedal when bleeding the rears.

In the FSM is says to depress the proportioning valve with special tool (J-26869), I plan to do this with a clamp, but when I look at the valve, it only sticks out about 1/32". Is this all it sticks out? Can someone pls have a look at theirs and tell me know long it is.....sorry for the personal question

yea that's about right, doesn't stick out much and doesn't travel in very much either. I'd say travel was less than 1/4 inch on mine.

There are W and S valves. Look at and it will explain which is push and which is pull. If you follow the lines up to the master cyl, then undo the one closest to the button while someone is pushing the pedal and the button should pop up about the time they hit the floor. (the fluid will eat paint!)
Tighten the line and see how the brakes feel. Also, manually adjust all the brakes (assuming drum) and make them drag a bit. Hit the brake and adjust them again (you have to center them to get the adjustment correct)
