Flush the Brake Fluid, just bleed it until it fresh fluid comes out the bleeder screws. The Manufacturers are high when they recommend the brake fluid to last the life of the car, it is significantly degraded within 3 years, let alone 10 years most cars are used, and 19 years? Forget it, if the brake fluid is the original its surely a mess.
NAPA have Rebuilt Calipers for $18 after you get your core charge back. It would cost about the same to rebuild them yourself, rebuilding calipers is much easier than most imagine, especially if they have phenolic pistons that Chrysler likes to use.
Obviously don't go cheapo on the rotors or pads, you don't have to buy the highest quality out there, but with brakes there are enough loss-leader inferior quality pads out there that I NEVER buy the cheapest pad offered no matter what supplier it is.
A hardware kit for the rear drums is a must also, the parts back there usually seize up if not cared for, especially within 19 years. Maybe turning the rear drums will help.
Check the rear wheel cylinders carefully, they often leak by this time, especially if the brake fluid is old and gummed up. New seals are only a few dollars, and the tool to hone them only a few dollars as well, you can do it with emory clothe, but its worth the couple of dollars for the tool. Rebuilding the rear wheel cylinders can do a lot for reliability, they have been the cause of almost every brake problem I have ever had in all my vehicles over the years. They are usually the cause of the mysterious brake leak you can't find.
Also, the Master Cylinder may seem fine, but they can often get corroded in farther down the bore of the cylinder, where the piston never travels, because you rarely push the brake pedal all the way to the floor. So when you bleed the brakes, the piston on the Master Cylinder stokes the full bore to the end, it passes over the corrosion, which cuts/chews up the seals on the pistons. Suddenly, your good Master Cylinder goes bad just after bleeding the brakes. Just something to look out for.
When you pull the front wheels and look at the calipers, look for the common pads wearing into the mounting ledges. That can cause the pads to stick and that can create all sorts of problems. Depends on the brakes you have, but if you have the worn down spots, most likely you'll have to replace the steering knuckle or repair it by welding in the worn spots and grinding/filing it back to its proper shape. There was a long thread on this recently, it would be good for you too read, do a search for "Mounting Ledges" and that should bring up the thread.
