Calipers hanging up...can I test them?

I have been having a brake gremlin show up every so often between my drivers side front and rear calipers. I haven't seen anything on the front since changing the brake hoses....probably need to do that on the back now. I have flushed the system...turned all four rotors, put on all new pads, re-lubed the glide pins, painted the e-brakes springs and tensioner in rear with nickel anti-seize compound...not sure what else to try. My rear drivers side is driving me crazy. I am to the point of replacement @ only (82K miles?)...Is there a way to check the calipers to see if they're okay...or should I just go ahead and replace? I know, the rotors could be warped, so replacing them too would be in order. I've checked the temps on the rotor that is hanging up and its around 650'F...probably not good. Let me know if you think I should replace them, and if so, any suggestions on where to get the replacements from. Thanks.

My passenger front went out on me at 55,000. I replaced it with a factory one, machined both rotors down and installed new Hawk Performance LTS brake Pads. I tried to loosen them and flush them, but nothing helped the caliper. Ended up replacing via Ford. I did not want to turn my rotors and put new pads and then have the caliper destroy my new pads and all. Good Luck

The way I check if a caliper is hanging up at work is my using a brake line clamp. You clamp the brake line feeding the bad caliper and then go take it on a test drive and if the problem goes away you know its that caliper. You can buy rebuild kits for the calipers and rebuild them yourself or get a new one from a parts house.

Pretty neat trick...but what if it is the brake line causing the problem?
