Fitted the New Pads ,all ok ,did a nice ride today and finished off on the freeway ,purposely did not use the rear brake when I stopped in the garage I felt the rear disc,it was warm ,as is the hub from the diff temperature ,I had a look at the two pistons the seem to be fairly well out of the calliper ,but the brake is not binding ,I will check the brake pedal rod that actuates the master cylinder Tomorrow to see if it is in need of adjustment.
