Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, engage the parking brake, and place wheel chocks around the rear wheels.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection:
- Remove the brake caliper by unscrewing the caliper bolts with a socket set.
- Carefully lift the caliper away from the rotor and support it with a bungee cord to avoid straining the brake line.
- Check the brake pads for thickness; if the pads are less than 3mm, replace them.
Replacement:
- Remove the old brake pads from the caliper bracket.
- Install new brake pads in the caliper bracket, ensuring they’re positioned correctly.
- Apply brake grease to the back of the new pads to reduce noise.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or excessive wear. If damaged, replace the rotors.
Remove the rotor by unscrewing the retaining screws if applicable, and slide it off the hub.
Install the new rotor, ensuring it is seated properly and secured.

5. Reassemble and Test

Reattach the brake caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications (typically around 25-30 Nm).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to ensure even tension.
Reconnect the negative battery terminal.
