Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and securely lifted using jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the wheel bolts.
Carefully remove the wheel from the hub.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it with a bungee cord (do not allow it to hang by the brake line).
- Remove old brake pads from the caliper bracket.
- Check the anti-rattle clips and replace if necessary.
- Install new brake pads in the caliper bracket.

Tools Required: Socket set, lug wrench, bungee cord, brake cleaner.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- If the rotors are damaged, remove the rotor by removing the retaining screws.
- Clean the hub surface with brake cleaner to ensure proper rotor seating.
- Install new rotors, ensuring they are aligned properly and secured with screws.

Tools Required: Torque wrench, brake cleaner.

5. Reassemble Components

Sub-steps:
- Reinstall the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications.
- Reinstall the wheel and torque the wheel bolts in a star pattern to the specified torque.

Tools Required: Torque wrench.

6. Final Check

Lower the vehicle and pump the brake pedal to seat the new pads.
Check the brake fluid level and add if necessary.
