power brake booster
I picked up a reman power brake booster for my 72 3/4 ton and noticed it didn't have an adjustable rod to the pedal. The one in my Ford has an adjustable rod. Anyone know if it matters. Has dual piston calipers in front and drum in rear.

Are the rods about the same length?
I used the adjustable. It takes a few install attempts to find the sweet spot. if you have it in too far, when you start running and the vacuum is good, your brakes will come on....smoke....slowing down....crap! lucky I had a flathead screwdriver with me to back off the rear brakes to get her home.
The opposite being that you push a little and nothing happens. Push a lot and maybe a little happens, but not as much as you want. Like a said, there is a sweet spot and it's not real big in my opinion.

I measured them and they are the same length. I went ahead and put the booster in and everything seems fine. When I brought the core back I made a comment to the guy about the adjustable rod. He said "well, you really don't it." With my understanding of the english language, that means you should have it. Anyway, I've owned the same style ford trucks for 30 years and don't ever remember adjusting that rod. Oh, well, it's in now.

I had to use a booster that would mate to my 67 Cab, and to the 69 Master Cylinder (disc/Drum) setup. In that transition, the adjustable helped.
I purchased a rebuilt booster for the 69, but it's bolt pattern did not match that of the cab/firewall. SO, I found a booster for teh 67, and used the 69s adjustable pushrod...it took some adjusting, but it works now. (well it would if I hadn't blowed up my motor :-)
