5. Slide the caliper off the upper dowel (which is the only thing left securing the caliper to the car) and secure it in the wheel well using a bungee cord or string in a location and orientation that minimally stresses the brake line.
Warning!In this step, you will be removing the caliper! Make sure to have a way to secure it up in the wheel well in such a way that the line is not stressed!
6. Remove brake pads out of the pad/caliper housing. They should just slide out of their tracks. There is one on each side of the rotor.
7. Clean both surfaces (front and back) of your rotor with brake cleaner and paper towel. Keep applying cleaner and wiping with new towels until the towel comes out clean. Use latex gloves for this step so that you don’t get your skin oils on the rotor after you clean the rotor surface. Make sure to clean all of the rotor surface. You will need to rotate the rotor to do this.
8. Now you will need to bleed your brakes.
Warning!During this entire step, do not allow the piston to recompress when the brakeline valve is open! If you do, you will introduce air into your brake lines.
9. Snug the c-clamp onto piston as shown in the photo below. Use the 21mm socket in between the clamp and the piston cup to help distribute the load.
