On a side note, interesting that ford never really changed that switch cause i had a mid 90's explorer that had that exact same switch on the pedal. I guess like I said in the initial post, not broke, don't fix it? LOL
I thought I would add that the brake switch that mounts on the brake pedal comes in several different versions, all appearing and installing the same. The difference in switches is the tension of the spring that is inside the switch housing. For example, power brakes take less pedal pressure so the spring is lighter tension as compared to manual brakes. This is important becasue if you install the incorrect switch, your brake lights may not be coming on timely which is dangerous. Springs are colored according to tension, but I don't recall what color is which tension. Just be sure to have someone check your rear brake lights as you apply pedal pressure. The lights should come on with little pedal travel or pressure.

Yeah, I named the incorrect part.
My Proportioning valve in litteraly right on my master cylinder (minimal tubing between the two)... must be something the previous owner did. I also have a distrobution valve...drums where converted to disc in the front.

Maybe I should re-do my brakes...🤔

Is it adjustable somehow?

Mine is a dual pin (2 wire)...
Yes, this is the 67-69 proportioning valve. Mounted a bit lower on late 67, and by the rear axle hose on early 67. And no, it is not adjustable, but it is rebuildable.

Amateur restorer. Well, sometimes I have been paid for it. But not right now.
