Gonna run it for a bit during the week and see if it frees off as its maybe just stuck from lack of use. Failing that will strip the brakes at the weekend and investigate.
Think I have cossie discs and std RS calipers but not sure as were already fitted when I bought the car. If the calipers are shot I would prefer toreplace with something new and better.
Would mondeo calipers fit straight on with new pads?
