Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the battery to avoid electrical issues while working.

2. Raise the Vehicle

Use a jack to lift the vehicle at the designated lift points.
Secure it with jack stands for safety.

3. Remove Wheel

Use a socket set to remove the wheel nuts.
Take off the wheel and set it aside.

4. Remove Brake Caliper

Locate the caliper mounting bolts and remove them using the appropriate socket.
Carefully slide the caliper off the brake rotor; do not let it hang by the brake line.
Support the caliper with a bungee cord or rope to avoid strain on the brake line.

5. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Apply brake grease to the back of the new pads to reduce noise.
Install the new brake pads into the caliper bracket securely.

6. Reassemble Brake Components

Reinstall the brake caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications (typically around 30-40 Nm).
Reinstall the wheel and torque the wheel nuts to the specified value (typically 120 Nm).

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.

8. Final Checks

Reconnect the battery and check for any warning lights.
Pump the brake pedal a few times to seat the new pads.
