Blazer rear brakes overheating

I have a 2000 4x4 Blazer....

I recently changed the rear brakes, and they're over heating....

they over heated the last time I changed them, until I redid the job...not that I did anything different.

any suggestions on avoiding the overheating on the next change?

The caliper pistons must fully retract freely and smoothly into the bores, if not, replace them as necessary. All rust needs to be removed from the guides that the stainless steel retainer clips fit in to. If they are not cleaned out thoroughly, the pads will bind. Do not reuse the old clips or guide pin boots. The guide pins and their bores need to be rust free and lubricated. Before the wheel is installed, put one hand on the caliper and slide it back and forth, it must slide very freely.

Those rear calipers usually need to be replaced with rebuilts due to the plastic piston getting stuck or jammed in the bore. Common problem with the design and on all 4 of mine I simply replace when pads are needed. In fact, buying "loaded" calipers that come with pads, caliper, bracket and slide pins are only about $55-60 and avoids all the problems associated with the rear brakes - I learned the hard way after fighting caliper and slide problems several times.

The caliper pins are froze up and that is the only thing I seen so far.You can get the caliper mount with the pins at certain auto parts stores since that is a common problem.
