Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Raise the vehicle using a jack and secure it on jack stands.

2. Remove Wheel

Use a socket set to loosen and remove the lug nuts.
Take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspect: Check the brake pads for wear; if they are less than 3mm thick, replace them.
Remove: Detach the caliper by unscrewing the caliper bolts using a socket wrench.
Replace: Slide out the old brake pads and insert new ones, ensuring they are seated properly.
Reinstall: Reattach the caliper and torque the bolts to manufacturer specifications (usually around 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Remove: If rotors are damaged, remove them by unscrewing the rotor retaining screws (if equipped) and sliding them off the hub.
Replace: Install new rotors, ensuring they are clean and free of grease.
Reinstall: Torque the rotor screws if applicable.

5. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to manufacturer specifications (typically 80-100 ft-lbs).
Reconnect the negative battery terminal.
