  6. Using a ratchet with18mm socket, unscrew two mount bolts holding the caliper in place.
  7. Use a stiff wire or a Velcro tie to hang the caliper of the steering arm so that it does not get damaged.

  9. Pull the pads out of the caliper
  10. Push the caliper pistons into the caliper. There are two pistons on each side of the front brake assembly, using a C-clamp and an old brake pad to distribute the pressure evenly. Take care not to damage the pistons.
  11. Insert the new pads into the caliper. If the pads came with the anti-squealing applicators – attach them on the outside of the pads (not the sides that will touch the rotors). Insert the pins and the spring. Secure the pins.
  12. Replace the caliper; secure it with the mounting bolts.
  13. Replace the wheel. Hand -tighten the lug nuts.
  14. Lower the car
  15. Tighten the lug nuts.
  16. Open the hood and remove the excess brake fluid

    The bolts holding on the calipers were really tough to get. I had to use a big breaker bar to get them loose. And at first I didn’t realize the pads on the front were very different from the pads on the back. Cranking the wheel all the way to the outside helped with access to get the bolts off quicker. Pay attention to how the spring goes on because the replacement pads don’t come with that spring or the little springs that hold the long bolt that goes throught the pads in place.
