Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads. If they are below 3mm, they should be replaced.
Remove Brake Caliper:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it using a bungee cord or wire to avoid stress on the brake line.
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Brake Rotor:
- If the rotor is scored or worn, remove the rotor by unscrewing the retaining screws (if applicable) and pulling it off the hub.
Install New Rotor:
- Clean the hub surface to remove any rust or debris.
- Install the new rotor and secure it with screws.

5. Reassemble Brake Assembly

Reattach the brake caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer's specifications (typically around 30-40 Nm).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

6. Final Checks

Reconnect the battery.
Pump the brake pedal several times to ensure proper brake pad seating.
