Master cylender 82 cj7

I went to replace my master cylender on my 82 Cj7 but every one i get from the parts store wont fit my brake booster. Does anyone know why this may be? I know alot of people put parts on these from all kinds of vehicles so im wondering if there might be a "common" brake booster or brake system that people liked to put on this model?

Why don't you take your old one with you to the parts store?

pictures may help ID it,,,, I used the OEM MC on an 89 xj booster, the bolt holes had to be modified a bit. There are many that are used to do this mod.

I did take it to the parts store and gave it to them as my core, by the time i was able to put the new one on they had already shipped out my old one. Im trying to find out what this brake booster came off of online but i doubt that i will find anything. The only markings on it is 2218A and i think it is a serial number not a part number.

Are there any other modifications done to the brakes? If so this could point took in a direction.

I had your same problem with the core. Match them up before you let go of your parts.

Rather than drill out the holes (getting metal shavings inside) NAPA (at least here) has a wide selection of adapters that will screw into the MC and the lines into them, take the MC with you. The NAPA here lets me go back and dig through the drawers until I find the fitting I want. Good luck!!!!

Note that there may be internal differences as well,,, and that may affect the braking ability of the jeep. I put one on and when I touched the peddle I almost went through the wind shield. All 4 33x13.50 TSL SS'ers locked and sliding, it is not on now,,,,,
