I think this is something we need.
This post will serve as a reference for anyone looking for brake upgrade information. I'll be linking to other threads where relevant as well as posting upgrade info to this thread.
If any SAS guys want to bring threads to my attention that are brake related, I'll add them in.
Front upgrades
Easy one is slotted rotors in the front. The rotors are already 11.14 inches in diameter. Which is plenty big enough to stop the truck. The reason for slotted rotors is that it allows the easier expulsion of heat and gasses produced by braking. So if you have to brake hard it allows the for less brake fade. There are also cross drilled options which puts little holes through the rotor, but to me those little holes are just something to fill with mud when wheeling. Then they're serving no purpose.

- Cost: $65.97 Each
We already have dual piston calipers. But, what if you want more stopping power?
96-04 Pathys have a 12" rotor and the same dual piston caliper. So that kind of move would necessitate 16" or larger wheels, but that may also be an option. Larger rotor == more stopping force.
The Z32 had a 4 piston caliper and almost identical rotor dimensions. I'm currently looking around to see the potential of a caliper upgrade. More pistons == more clamping force. If those calipers will work, they'd still fit under 15" wheels. I'll be ordering one of these soon and we'll see if they fit.
Another easy upgrade is stainless steel lines. The steel webbing over the rubber line prevents expansion of the line and ensures that all of the hydraulic pressure makes it to the actual brakes. The kit linked below covers the stock setup on the X. The longer rear line is required for anyone with a full 3" suspension lift in the rear and suggested for anyone with a PML using longer shackles.

The picture just shows the rear line but the description reads all three w/ suspension lift. Thanks to SRStaff for pointing that out.

Rear Pathy disc upgrade
I've made a How-to thread for the swap. It can be found here -> Pathfinder Disc Brake Swap How-To
This thread will include a full parts list and instructions on the swap. It's an involved process requiring special tools and some mechanical know-how.

Master Cylinder Upgrade
This one comes from the SAS side of things.
Credit to Jbat for the information.
1999 Dodge RAM 1500 master cylinder. Same bolt configuration, requires two line adapters, has a 1¼" bore, and larger reservoir. Stock X master cylinder only has a 1" bore. The larger bore pushes more fluid down the lines. Also, on the front brake line you will need a m10x1.0 bubble flare to m10x1.0 inverted flare adapter and on the rear brake line you will need a m12x1.0 bubble flare to m10x1.0 inverted flare adapter. Alternatively, you can cut and reflare with the appropriate flare nuts (if you're so inclined).
With going to rear disc, this may be a good upgrade as well and I will investigate further.
