1. Loosen the wheel bolts a half turn 2. Jack up the car and stick in an axle stand 3. Remove the wheel bolts and remove the wheel, be aware that the wheel may be stuck to the hub (loosening the wheel bolts before you jack up should allow the wheel to break the corrosion seal) 4. Using a flat screwdriver, pry the pads back in the caliper, to clean any dust and dirt from the pad slides 5. Using a 12 (possibly a 13mm) spanner loosen the caliper retaining bolts and swing the caliper out of the way 6. Lever out the pads, doing 1 side at a time, taking notice of the position of the anti rattle clips (new ones are usually supplied with pads, if not, the old ones are perfectly fit to reuse) 7. Using a brake winder press in the caliper piston (do this slowly, as the brake fluid presses back into the brake fluid pot, via the master cylinder and if done too quickly, it has been reported that the seals could turn) 8. Reassemble the caliper, using the new bolts supplied 9. Before you refit the wheel, coat the mating surfaces in a light coat of copper grease 10. Coat the threads of the wheel bolts with WD40, tighten up hand tight and torque/tighten them when the wheel on the ground 11. Repeat for the other side
