Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface and secured with wheel chocks.
Disconnect the battery if necessary for electric brake systems.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check thickness; if below 3mm, replace them.
Remove Old Brake Pads:
- Unscrew the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Install New Brake Pads:
- Apply brake grease to the backing of new pads to prevent squeaking.
- Insert new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Rotor:
- If the rotor is damaged, remove the caliper bracket bolts and take off the bracket.
- Unscrew the rotor retaining screws and slide the rotor off the hub.
Install New Rotor:
- Clean the new rotor with brake cleaner to remove any protective oil.
- Position the new rotor onto the hub and secure it with retaining screws.

5. Reassemble Braking System

Reattach the caliper bracket and tighten bolts to the manufacturer’s torque specifications.
Reinstall the caliper over the pads and secure it in place.
Replace the wheel, hand-tighten lug nuts, lower the vehicle, and then torque the lug nuts to specifications.
