Master Cylinder & Booster for CJ

[Kim Dawson]

A few years ago I bought a used TJ booster & MC thinking I would use it on a CJ. I made an adapter bracket that would put it in the right position to fit the CJ pedal. This all looked very nice until I put it on the car. I can see that the booster will interfere with the hood. I see on ebay lots of new MC with boosters. Mostly 8", with either flat top MC or GM type MC. I don't plan on tire larger than 31". Any thoughts on which set-up would be better?

I bought the mc/booster combo from Morris. It's been good, but sits quite a distance from the firewall.

Like Master Power Brakes, need to call for CJ order vs web Masterpower

I have used this one as well, will lock up 33's without an issue and is A LOT different than stock, which is also fine, but never designed to stop the larger rolling mass.

These just have more ooomph to them for not too much money and pretty easy to install in a day.

Thanks for your replies. I see ones that look the same on Ebay for less, $164.99, which are made in China. Are all of these made in China? And are all of these the same?

I am almost certain the one CB and I referenced is made in China, distributed at least in part by MBM brakes, and there are individual parts available separately. I had to replace my booster recently and found that on eBay for $80 or so. I just had to cut the threaded pushrod down. You might find that to be the case if you buy the cheaper varieties. Just remember to thread a bolt on before cutting, to make it easier to set the threads when you unscrew it.
If there are good reviews that mention CJs, I'd say go for it.

I bought that one off of eBay, and it works great. I did have to cut the female threaded part of the rod off about an inch. Otherwise the pedal would’ve been too high. But once I made that modification, everything works perfect. I couldn’t be happier with the stopping power.
