YJ power brake booster conversion to CJ-7

Hi everyone. New here to Jeep Forum. Seems like a good tool for jeep enthusiests. Anyhow, I just bought a power brake booster from a 95 Jeep YJ and was planning on installing it to my jeep. It appears that all the holes line up, so that eliminates some trouble. Does anyone know what mods need to be made to the push rod? I have heard from some sites that the rod will not need to be adjusted, then I have heard from other sites that the rod will need to be cut and welded to make it about 1/2" longer. Any help?

Thanks

Installation complete

Hi. Well, it took some time, but the installation of the YJ power brake conversion is complete. If anyone has any questions, please let me know.

Thanks,

Jeremy

And your opinion on this mod?

We originated this mod and every once in a while we'll see a thread where someone complains about it (usually spongy pedal).

Hope you like it.

I rode in my first jeep with this mod last weekend. WOW - The pedal was very very soft, but it would throw you through the wind shield. My borther in law jsut bought it, so not sure how the mod was done. The pedal you can get used to, and the brakes were powerful!

My pedal was not mushy at all. I did the adjustable pushrod deal where I welded a 1/2" nut (13 thread count) on to the push rod. When I cut the push rod, I left about 1.5" and took a die to thread it. The holes on the YJ booster matched up perfectly, so luckily I did not have to drill.

The only problem I had was the size of the booster. I have the 258 and the air filter housing got in the way a little. But was fixed with a mallet (professionally done). I am going to get a smaller air cleaner housing and everything should be good to go.

I recommend this mod to anyone who wants a whole lot more power with their brakes. The first time I hit the brakes on my test drive I almost flew in to the window because I was not used to it.

Awesome results for an awesome price. Fluid, adaptors, power mc, and brake line (Had to buy one because I broke one) cost me about $120 compared to the kits you see going for $400 or so.

Good Luck.
