well you need to once a year clean them with brake cleaner or just some Dub-D-40.
check if the sliders are pushing back out if not you need that part, but it has to be clean and if you can go to a local bone yard and get one your better of cause it would be preset.. again keep em dubbed once a year.
If the caliper is sticking or you can't get the piston pushed back in it's best to just buy a new caliper.
The best thing you can do is replace the caliper.
slider needs high temp grease.
just replace the whole caliper.
If the caliper is sticking or leaking it is possible to buy a rebuild kit and replace all parts that are worn inside. If the caliper has a cracked or broken housing then the unit can not be repaired and must be replaced.
If the caliper piston is sticking, replace the caliper. If the caliper yoke is sticking in its guides, clean the guides with a wire brush. Some caliper yokes make use of shims and bushings in the guides to reduce friction, these may need to be installed or replaced. Check with your dodge dealer regarding those shims.
Have them turned. If the caliper is not sticking they shouldn't warp again
first replace brake fluid if that does work take off caliper spray it with wd40 n move it in n out that should solve the problem.
If the front brake caliper is sticking, the disc may be uneven. Brakes that are left to scrape on the disc for a long time before they are changed will damage the disc enough to cause sticking or slipping.
To replace a faulty brake caliper with a new caliper or a rebuilt caliper and assuming that is all it needs, a garage would probably charge you one hour of labor plus the cost of the caliper and brake fluid. Call your local auto parts store to get a quote on the brake caliper.

I had the same issue and it turned out to be that the break caliper was sticking and needing replacing.
