Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during work.

2. Inspect and Replace Brake Rotors

Remove the Wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove lug nuts using a socket set and take off the wheel.
Check Rotor Condition:
- Measure rotor thickness using a micrometer; compare to OEM specifications.
- If warped or below thickness specifications, proceed to replace.
Remove Old Rotor:
- Unbolt the caliper and hang it securely (do not let it dangle by the brake line).
- Remove caliper bracket bolts and take off the bracket.
- Unbolt and remove the rotor.
Install New Rotor:
- Clean the new rotor surface with brake cleaner to remove any protective coating.
- Install the new rotor and secure it with bolts to the hub.

3. Replace Brake Pads

Remove Old Brake Pads:
- Slide out the old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease on the backing of new pads.
- Position the new pads into the caliper bracket.
Reassemble Caliper:
- Reattach the caliper over the new pads and tighten bolts to manufacturer torque specifications.

4. Inspect and Repair Suspension Components (if necessary)

Check for Wear:
- Inspect tie rods and control arms for play and wear.
Replace Worn Components:
- If any components are damaged, remove and replace them with new parts, ensuring proper torque specifications.

5. Wheel Alignment

After replacing components, perform a wheel alignment to ensure proper handling and tire wear.
