Master Cylinder swap

[Ridgerunner]

I'm need to replace my stock MC on the yj because its leaking when not on level ground. I have read a few articles about swaping in 85 F350 van units with a little mod work. Just wondering if any one has performed this swap or knows if its an worthwhile upgrade.

I think there are a handful of different ones you can use, Pirate4x4 search would be best, but for my TJ I used a Dodge one...had to put in a 5/8" slug inside it, but otherwise it bolted on...don&#39;t know about a YJ...

Did you notice much improvement over the stock Mc?

I never bothered to run my stock master cylinder when I upgraded the axles. I went to a dual piston front caliper and figured with the increase in volume I&#39;d better get something designed to work with them. But, never have had better brakes&#33; Just need some rear disks now...
