On the brakes. Assuming you haven't done any work to them I would guess your master cylinder is going out. It's not pushing the fluid with enough pressure to get the brakes to bite. This is likely caused by an internal leak. That's about all I can come up with if you aren't loosing any fluid.
I doubt its the pads. You could replace them anyways. There cheap enough and that would eliminate that hypothesis.
I agree. Sounds like the master is bad.
Here's a MeanMax thread on the STUD replacement:
Images appear broken, but you get the gist of it.
Below is a thread with some great links on upgrading your vacuum assist and master cylinder from your current set up to a 95 YJ brake set up.
If you are going to be replacing it, why not upgrade?
