Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery to ensure electrical safety.

2. Remove Wheel

Use a jack to lift the front or rear of the vehicle, depending on which brakes are making noise.
Secure the vehicle with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and support it with a bungee cord or rope (do not let it hang by the brake line).
- Measure the thickness of the brake pads; if they are below the manufacturer's minimum thickness (typically around 3mm), they need replacement.
Replace Brake Pads:
- Remove the old pads from the caliper bracket.
- Install new brake pads into the caliper bracket.
- Apply brake grease to the back of the pads where they contact the caliper to reduce noise.
- Reinstall the caliper over the new pads and tighten the caliper bolts to the manufacturer’s torque specification (usually around 30-40 Nm).

4. Inspect and Replace Rotors (if necessary)

Check the rotor for grooves, cracks, or significant wear.
If the rotor is damaged, remove it by unscrewing the rotor retaining screws (if equipped) and sliding it off the hub.
Install the new rotor, ensuring it is seated properly.
Torque the rotor screws if applicable.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Tighten lug nuts to the manufacturer’s specifications (usually around 100-120 Nm).
Reconnect the negative battery terminal.
Test the brakes gently at low speed to ensure proper function.
