So how come after I hit my brakes real hard the pedal will be nice and firm for the next day or two?
brakes get nice and firm after a panick stop?

Is the brake feel firmer or is there simply more bite? If you mostly drive gently, then it may be that you're allowing some pad transfer to the rotor, similar to bedding-in. Most people I know have no idea what bedding-in is, and simply drive their cars normally after a brake job.
I've noticed a marked improvement in all of my vehicle's braking performance after doing a few hard stops and then allowing the rotors to cool off by driving gently. This especially helps if I've been driving extremely gently for an extended period of time.

still stops the same just firmer pedal.
You probably have air in the system. This happens to me every time I use a vacuum bleeder to do a brake flush.

Adjusters? Where is the adjuster on a hydraulic brake system?
I have not done brakes in many years, but the last time I did, all drum brakes still had automatic self adjusters that seam to ratchet up a click if you hit the brake fairly hard while the vehicle was moving backwards. Usually they did not adjust a click for forward stops. I am not sure if a hard forward stop would cause them to adjust.
If the vehicle has four wheel disc brakes then it would not have these mechanical adjusters.

umm (Pure guess work here...) fluid getting hot enough to evaporate moisture in the sys, but not enough to boil the fluid itself.
as i said, purely guessing.

Maybe you have a caliper pin that's mostly seized up. If you have your typical single piston caliper that floats on two pins (or similar hardware), if one pin freezes the brake still kinda works but will be spongy and if you keep it up the pads will get wedge shaped and jam themselves all funny.
When you slam on the brakes it frees that pin up and the caliper retracts to a position closer to the rotor.
Naturally, you want to check this out.

Hydraulic brakes are almost 100 years old. And adjusters are normal .
Disc brakes don't often have them ,but drums do.
To the OP - Could be rear drums that tightened up, a nice hard seating or cleaning, or overcoming sticky parts temporarily.

1) Its a Chrysler . Be lucky it stops at all.
2) Its a Dodge. Be lucky it stops at all.
3) Your fluid is almost worn out. Air is moving through the system. On a panic stop it gets integrated for a bit back into the fluid , then in a few days it migrates back out.
4) you are imagining it.
5) Buy a real mans truck and you won't have that problem.

The water vapor would lead to a spongier pedal feel, since it is compressible, unlike water and brake fluid.

You probably have air entering though a faulty component somewhere. Slamming the pedal slams the air out, then it slowly comes back in. I had a car with a hydraulic clutch behave this way, the concentric slave had gone out, eventually it got bad enough that you had to bleed it before going anywhere and pump the pedal at lights to get it back into gear.
Check the brakes on all 4 wheels for evidence of leaks, crawl under the dash and loot at the master cylinder push rod, is it wet with brake fluid?

Agreed! I've ran into this issue many times. Caliper pins will cause this issue. As for the air? You would have to pump the pedal quickly to achieve a firm pedal. The firm pedal would cease to exist after releasing the brake and simply reapplying. Moisture??? maybe is it's below freezing.
