Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface and securely supported with jack stands.
Disconnect the battery to eliminate electrical hazards.

2. Remove Wheel

Use a lug wrench to loosen and remove the lug nuts.
Carefully remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor. Support it with a bungee cord or wire to avoid straining the brake line.
Inspect Brake Pads:
- Check the brake pads for wear. If they are below the manufacturer’s minimum thickness (usually 3mm), replace them.
Install New Brake Pads:
- Remove old pads and install new pads. Ensure they are positioned correctly in the caliper bracket.
- Apply anti-squeal grease to the back of the pads if required.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Rotor:
- If rotors are scored or warped, remove them by unscrewing the retaining screws (if present) and sliding the rotor off the hub.
Install New Rotor:
- Clean the new rotor with brake cleaner to remove any protective coating.
- Slide the new rotor onto the hub and secure it with retaining screws.

5. Reassemble and Test

Reattach the brake caliper over the new pads and rotor, tightening the mounting bolts to the manufacturer's torque specifications (typically around 80-100 lb-ft).
Reinstall the wheel and tighten the lug nuts in a star pattern to ensure even seating.
Reconnect the battery.
