undo brake pipe securing bolts on caliper x2. undo caliper bolts, remove brake pads. undo caliper housing bolts. these bolts are tight all the way out, you will need big breaker bar and lots of brute force. undo brake disc retaining bolts that double up as wheel locators. bash off disc. replace disc and refit all bolts. push back both pistons in caliper and fit new pads. refit wheel.
