I would not use any oils on the bleeder screw threads after this is replaced..the small amount of non compatible oils reacting with the brake fluid is harmful to the braking system componets ..
I am a person who uses anti sieze in most of my assembly of vehicle parts that have rust issues , but this is one area that is not to be used ..
since you have this pulling it is best to replace both calipers in the front in pairs ..this would be the correct way to repair your brake issues...
removal of the bleeders if siezed is to heat the bleeder until it starts to glow red slightly, with a small hand held propane torch.. then with a 6 point box wrench or socket gradually increase torque to remove ..if it binds repeat...the heat will expand the fitting, the cold wrench socket will cool shrink the fitting , as this shinks slightly you will get it to loosen ..
with the bleeder removed it would be best to remove caliper and using 10-20 psi of air with a small foot pump work the caliper and if necessary remove the piston to inspect the bore for rust ..any rust in the calipper bore it is best to replace ...but do this in pairs not just one side ..
