Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, brake cleaner, torque wrench, replacement brake pads, and rotors if necessary.
Ensure the vehicle is on a level surface and securely elevated using jack stands.
Disconnect the battery to prevent electrical issues.

2. Remove Wheel

Use a socket set to loosen and remove the lug nuts.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using the appropriate socket.
- Carefully slide the caliper off the rotor, ensuring not to stress the brake line.
- Remove the old brake pads from the caliper bracket.
Replace Brake Pads:
- Clean the caliper and bracket with brake cleaner.
- Install new brake pads in the caliper bracket, ensuring they are seated properly.
- Reattach the caliper over the new pads and secure it with bolts, tightening to manufacturer specifications (usually 25-35 Nm).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are damaged, remove the rotor by unscrewing the retaining screws or bolts.
Clean the hub surface to ensure proper rotor seating.
Install new rotors, aligning them correctly, and secure with retaining screws/bolts, tightening to specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 100-120 Nm).
Reconnect the battery and perform a brake fluid check if necessary.
