I just installed a new booster on my truck. I think it was $75 from Amazon. You can get them with the master cylinder but it sounds like that ship has sailed.

Well again the heat, heat index, humidity and rain have not been my friend these last few days and not much has been done. Brake pedal is still pretty soft but I did manage to "test" the booster. It has a pretty strong vacuum and I can't pull the hose out of it but once the engine is off I can pop it out with a fairly large hiss and I don't hear anything leaking around it with the engine off so I think it's good. Soft pedal might caused by some trapped air in the master.
That plug actually showed up and I installed it so now I have a working fuel gauge.
I managed to address the valve cover leak, it was slightly tweaked by someone over tightening the bolts.
That's about as far as we were able to get before it got too hot the other day. Thursday looks to be a little cooler so hopefully we can get this thing buttoned up...

It's been disgusting here, too. I still manage to get an hour or so in after work every day. But, I don't work outside all day like you do.
There's an adjustment between the booster and the master cylinder. You did check that before installing the master, yes?
If not, you can still check/adjust it as the master can be unbolted from the booster with the lines still attached. But, yeah, soft pedal sounds more like air.

If you re-bleed the system and the issue is resolved, then it was air. If not resolved, then it might be something to check, the push rod could be slightly short.

When you bolt the master cylinder to the booster, there's a push rod that protrudes from the booter (the rod actuates the master cylinder). The tip is adjustable although my shop manual does not mention how to adjust it (I think the shop manual for my '85 Ranger had the procedure) or what the measurement is supposed to be. IIRC, the rod is supposed to be just over an inch (1 1/8"?) so that it engages and disengages the master properly. I checked my new booster and it was spot on so maybe they come pre-set?

This tool is like a U with a measurement in the center. You fit the U over the rod so the "feet" set on the booster and the rod should just touch the inside of the U.
The measurement is just under 1 inch something like .9xxx IIRC
Think I set mine a pee pee hair under the 1" mark and it has been ok.

I’ve been trying to upload a screenshot from my Haynes manual since last night but I guess the file type isn’t allowed as it just hangs in the process. Either way, per the manual, the measurement is 0.995” of exposed pushrod from the booster.

You can always take a picture of the page and load it like you load pictures to your files.
