On Mondeo 2003 TDi the rear offside caliper screws back in
anti clockwise. On rear nearside screw them in clockwise.
If you give a few turns in wrong direction they come loose and
you have to apply pressure after seating correctly and turn to send them back. It is a long job if you dont have correct tool.Dont turn
too fast or gaiter will split. Apply wd40 to help caliper spin in rubber gaiter.
