Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, caliper gauge, socket set.
Safely park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if you will be working on electronic components.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using a lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts with a socket set.
- Carefully slide the caliper off the brake rotor.
- Inspect the brake pads; if they are worn down (less than 3mm thickness), replace them.
- If replacing, slide out the old pads and install new pads, ensuring they are properly seated.

4. Check and Replace Brake Rotors (if necessary)

Sub-steps:
- Inspect the rotors for scoring or warping. If damaged, they should be replaced.
- Remove the rotor by unscrewing the retaining screws or caliper bracket, if applicable.
- Install the new rotor, making sure it is securely fastened.

5. Clean and Reassemble

Sub-steps:
- Clean the brake components with brake cleaner to remove dust and debris.
- Reinstall the caliper over the new brake pads and secure it with the caliper bolts.
- Reattach the wheel and tighten the lug nuts in a crisscross pattern.

6. Final Steps

Lower the vehicle and tighten the lug nuts to the manufacturer's specified torque value.
Reconnect the battery if it was disconnected.
