• Sub-steps:

  1. Loosen wheel lug nuts with a lug wrench.
  2. Raise the vehicle using a hydraulic jack.
  3. Secure the vehicle with jack stands.
  4. Remove the lug nuts and take off the wheel.

• Tools Required: Lug wrench, hydraulic jack, jack stands

3. Inspect and Replace Brake Pads

• Sub-steps:

  1. Remove the caliper bolts with a socket set.
  2. Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).

  4. Install new brake pads, ensuring they are seated properly.

• Tools Required: Socket set, bungee cord

4. Inspect and Replace Brake Rotors

• Sub-steps:

  1. Measure the rotor thickness with a micrometer to check for warping (minimum thickness should be specified in the service manual).
  2. If the rotor is warped or below minimum thickness, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
  3. Install the new rotor, ensuring that it is properly seated and aligned.

• Tools Required: Micrometer, socket set

5. Reassemble and Test

• Sub-steps:

  1. Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer's torque specifications.
  2. Reattach the wheel and hand-tighten the lug nuts.
  3. Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
