Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Engage the parking brake and place wheel chocks around the rear wheels.

2. Remove Wheel

Sub-steps:
- Loosen lug nuts using a socket set.
- Raise the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Sub-steps:
- Check the brake rotors for warping using a dial indicator; replace if the runout exceeds manufacturer specifications.
- Examine brake pads for even wear; replace if they are uneven or below minimum thickness.
- Inspect brake calipers for any signs of sticking or damage; clean or replace as necessary.

4. Replace Rotors and/or Pads (if necessary)

Sub-steps:
- If rotors are warped, remove the caliper bracket bolts using a torque wrench and slide the caliper off.
- Remove the old rotor and install the new rotor, ensuring it is properly seated.
- Reattach the caliper bracket and torque to manufacturer specifications.
- Replace brake pads, ensuring they are correctly aligned within the caliper.

5. Reassemble and Test

Sub-steps:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and then tighten all lug nuts to the specified torque.
- Pump the brake pedal to seat the pads properly before driving.
