Front passenger brake seized up

Having had about ten seized brake calipers on my 1999 Jeep Grand Cherokee over a period of ten years, I am the self proclaimed expert on this subject. I carry a slender pry bar about two feet long, 3/4" wide and 1/4" thick with maybe a 20 degree bend on the end. (It's a small tire tool.) I can insert the tip under the thin gap on the outer edge of the caliper and rest the heel of my bar against the rotor. Now pressing the handle toward the vehicle firmly you should feel the pistons (two) compress slowly, gently. Don't go too far and loose too much brake pedal. Drive carefully to the repair shop trying not to use much brakes if any. It may take 2-3 pumps to get brakes...be ready. Consider replacing the mate on the other side and check the rears. Carry a spray bottle of water to cool a hot rotor faster. It's those darned phenolic piston calipers that cause this. Chrome pistons are not available for this Jeep. Mine are under fully warranty but I still carry a pry bar and good pair of walking shoes. Good Luck my friend.
