Caliper drag

how long since the brakes were rebuilt?
the pistons should only move in about 4 thou and the caliper o ring should go back to its original shape and retract them.Maybe the caliper race is worn and needs to be filed flat or add a bit of silicon lube?

Well, probably about 10 years old since installed and they were new (remanufactured) when installed. I will look at them closer.
