Question about 1994 Ford Explorer Limited
How do I do this after a break job with booster change? Also how do I do the pushrod measurements to replace the master cylinder & booster? THANKS
Hopefully the push rod,need not be changed,if so,it needs to set with light pressure on the master,with the brake pedal up,all the way.Now ,bench bleed the master,then install it to the booster.Then connect the lines to the master,and bleed them ,one at a time.Check master reservoir often,not to let it get low.Then start at the right rear,and bleed,then the left rear,then the right front,and then left front.If it has rear SHOES,make sure they are adjusted,good,so that the brake pedal is high enough.I hope this is helpful,if so,please let us know,thank you.

To adjust the rod on the booster: Install the booster. Put a dab of grease on the tip of the rod. Bolt the master cylinder in place then remove it. It should contact the grease without pushing all of it off. In other words, you want the rod very close to the master cylinder plunger without actually touching it unless the pedal is pressed. As for centering the differential valve, Once everything is repaired, open all bleeders and leave the lid off of the master cylinder. See if fluid runs out of all of the bleeders. Most of those valves reset themselves. If it comes out of two but not the other two, the valve is still tripped. Reinstall the cap on the master cylinder and stab the brake pedal several times. If that doesn't reset it, find the valve and push or pull the pin sticking out of the end (it will only move one way) It should stay put in the center once it's released. Then, remove the cap again and keep adding fluid, closing the bleeders one at a time as they start dripping. Once they are all closed, proceed with bleeding as usual.
