Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery (if working on ABS or electronic systems).

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel lug nuts using a socket set and lift the vehicle with a jack.
2. Secure the vehicle on jack stands.
3. Remove the wheel to access the brake assembly.
4. Inspect the brake rotors for warping using a run-out gauge or visually for scoring.
5. If warped, remove the caliper (using a socket set) and support it with a bungee cord (do not let it hang by the brake line).
6. Remove the brake rotor (may require a hammer to tap off if stuck).
7. Install new rotors, ensuring they are properly seated.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Check the thickness of the brake pads; replace if below manufacturer's specifications.
2. Remove the old brake pads from the caliper bracket.
3. Apply brake grease to the backing of new pads to reduce noise and ensure smooth operation.
4. Install the new brake pads into the caliper bracket.

4. Reassemble and Torque

Sub-steps:
1. Reinstall the caliper over the new pads.
2. Torque caliper bolts to manufacturer's specifications.
3. Reinstall the wheel and hand-tighten lug nuts.
4. Lower the vehicle and torque the lug nuts to the specified value.
