What do I have and how can I make it work?

I have swinging pedals setup and a power brake setup that I got for free. I bolted it up and the piston rod is way too long to actuate the brake booster. So if you guys could tell me what I have and if I can make them work together? If not then what do I need to swap out?

Well, it looks Jeepish, but I would guess that it's not from a CJ. An aluminum master cylinder indicates it's relatively modern, like 80s or 90s at the oldest. Maybe from an XJ? You may be missing a standoff that goes between the firewall and the brake booster, and moves the pushrod to the proper position. Or they could simply be mismatched parts.

 

Oh yes they are mismatched. The pedals are out of a CJ but I don't know the model or year. I have no idea about the brake booster only that the bolts lined up. So, there might be a spacer? As for the rod... the post on the pedal arm, that is supposed to attach to the rod, pretty much touches the "piston" that sticks out of the rear of the booster.

 

The bolt pattern is fairly standard. That the booster bolts up doesn't tell you a lot. Looks to me like the angle of attachment to the push rod is all wrong for this application though.

The pedal assembly is the valuable part of this. Not knowing where the booster and cylinder come from is something of a problem, should they need service. Using a used master cylinder is a little dicey IMO, but you could try it. Boosters tend to be fairly durable, so it's likely it will be ok. But I would not use it if I did not know what it came from.

Assuming this pedal assembly is from an intermediate CJ, the boosters for those years are impossible to find new and very difficult to find used, but new master cylinders are easy to source.

 

If I was going to mount the pedal assembly to in my CJ2A is there a master that you'd suggest? I have 11" drums now and have no plans to change to disc at this point.

 

That looks like the same pedal assembly I have in my 2A. Mine came out of a 74 CJ5. I also took the axles from that same jeep with 11 drums. I set it up with a Vanco booster and Master and it stops great. The only issue I see is the price. I think I paid Vanco around $400. For a while I was thinking about swapping to discs, but I see no reason to now.

 

I know it would be hard to find now but I have a booster from a Chevy Monza bolted to a pedal from a Chevy Citation(conversion done close to 20 yrs ago). Also the master cyl from a full size with disc/drum but you could do the same with a 70's era full size drum/drum for the larger piston.
