Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Remove the Wheel

Tools Required: Socket set, lug wrench
Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Remove Brake Components

Tools Required: Socket set, brake caliper tool
Remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the rotor. Support it using a bungee cord or rope to avoid stretching the brake line.
Remove the brake pads from the caliper bracket.
If necessary, remove the caliper bracket by unscrewing the bolts.

4. Inspect and Replace Parts

Inspect the rotors; if they are scored or below the minimum thickness, they should be replaced.
If brake pads are worn to the indicator or damaged, replace them with new ones.
Apply brake grease to the back of the new brake pads to prevent noise.

5. Reassemble Components

Reinstall the caliper bracket (if removed) and torque the bolts to manufacturer specifications.
Reposition the caliper over the new brake pads and rotor, and reinstall the caliper bolts; torque to manufacturer specifications.
Reinstall the wheel and torque the lug nuts in a star pattern.

6. Reconnect Battery

Reconnect the battery terminals securely.
