We are seeing more and more sticking calipers. The Rams and Dakotas are notorious for it. I have heard that they are easy to rebuild. But I usually just go to the pick-a-part yard and pull obviously remanned ones for $10 a piece.

I’ve cruised a pick part lot and have never seen anything majorly diff.

That`s probably why most manufacturers suggest replacing or flush of the brake fluid often that 90% of the people don`t do. I think my VW was every two years or so. Buttt to REALLY FLUSH the system completely.... wouldn’t you have to unattach each caliper and turn it 180 degrees? I’ll betcha very VERY few people do that !!

I've only ever had the problem on two Chrysler products; a Dakota and a Grand Cherokee. Both have the phenolic caliper pistons Chrysler insists on using to save a few pennies. Both rear calipers on the Grand Cherokee stuck on trips at different times. One I had to change in the parking lot of an Advance Auto parts store in 95 degree heat halfway to my destination. Never an issue on any other brand of car I owned. So YOU are known to carry around IN YOUR CAR a big 8” C clamp too ?

On my '93 Dakota, I was having a problem with the right front hanging up. Being cheap, I ran the piston in and out (just short of popping it out) several times before putting everything back together. When I bled the brakes, I bled until I had clean fluid. Seems to have worked. Aside from no more heat and smoke, another sign is that the truck picked up a solid 1 - 1.5 MPG. I'll take what I can get! Oh, and I use a steering wheel puller like this and an old pad to push the piston back in. The last time I used a C-clamp, with nothing more than hand strength, it punched thru the back of the caliper. It really didn't feel like I was cranking on it THAT hard. Never had an issue pushing it. Easier to carry too.

It's important to be able to think and improvise when you're on the road and you don't have access to all of your tools. The lug wrench worked well enough to be able to pry the brake pads far enough apart so the old pads could be removed from the old caliper, and the new (rebuilt) caliper already had the piston retracted. No need for an eight inch C clamp.

The remanned calipers usually have a different finish to the metal. You can typically tell that they are not as old as the vehicle, especially after seeing a few original ones. And then the remanned ones often have a tag or sticker on them. If there are enough of the vehicles to choose from, sometimes you can score shiny, fairly new ones.
Just a few weeks ago, one of the calipers on our work Town and Country started dragging. I had to go to two different yards, but I found a fresh kill Grand Caravan with a nearly new complete front brake job. Calipers, hoses, pads, and rotors all for $40.
But it does take time to find and pull those deals. The only way it probably makes sense for most folks, is if it there were more than just those parts needed.

Not sure about 07 charger, but being a first generation LX maybe it has the same 2 piston Aluminum PBR calipers with phenolic pistons as the last 2 05 Magnums I've had.
If it does, there's probably not going to be any corrosion, but sometimes the Plastic pistons develop odd marks in the sides which cause them to stick. I haven't been able to figure out where the marks come from but they did it twice. Might even be my fault, I don't know.
Anyway it was the easiest caliper rebuild ever. 4 bucks for seals, 4.50 for new pistons, 99 cents for a copper washer. Take apart and replace the components. Nothing there to hone and no corrosion at all......

Maybe when you install the new pads you are cocking the piston or using your clamp to push the piston back too far. With all the brake jobs I have done I have never had a caliper stick. Maybe just lucky, maybe something to due with the environment the vehicle lives in. I don't know. I do know that we see sticking calipers on vehicles irregardless of the time frame of brake service or even on ones that have never had the brakes serviced. But it seems some brands tend to have trouble with the hoses, while others tend to have trouble with the calipers. And then some models have few, if any, of these problems. But we see more problems with the calipers it seems on these late model Mopars. But, fortunately, we aren't the only ones experiencing the issues. Which means that we are very likely to find replacement parts for cheap at the pick-a-part yards.
