gonna swap disc on the 8.25 that's going in my 89 xj. do I need to change the master cyl or car I get away with just the proportioning valve set up from a zj I think it is?

Just the guts of the prop. valve from the ZJ you pulled the brakes off of.

When I did my disc swap, I tried it with out the prop valve first and never saw a need to change it. So, I'm still running the factory prop valve but my xj is strictly off road so road manners don't matter to me. I think that the biggest issue with not swapping it is that it becomes easier to lock up the rear brakes, especially on wet roads.

In my 98 the brakes seemed good enough & I didn't swap out the guts.

I'll do the disc swap and see how it is because I still have the stock master that's a single diaphragm

I just finished doing the Liberty rear brake swap. It was a bolt on. No modifications at all. Just went to the JY and pulled the rear backing plates (with e-brake cables still attached) and calipers. Mine were from a 2007 Liberty. I decided to purchase new rotors and brake pads. Ended up costing about $200 total. Here is the link to the write up.
