Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Disconnect the battery for safety.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check for minimum thickness (usually around 3 mm).
- If worn, proceed to replace.
Remove Old Brake Pads:
- Remove caliper bolts using a socket set.
- Slide caliper off the rotor and support it with a bungee cord (do not let it hang).
- Remove the old brake pads.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads.
- Insert new pads into the caliper bracket.
Reinstall Caliper:
- Reposition the caliper over the new pads and secure it with the caliper bolts. Torque to manufacturer specifications (typically around 20-25 lb-ft).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are damaged, remove them by unscrewing any retaining screws and sliding them off the hub.
Clean the hub surface before installing new rotors.
Install new rotors and secure them.

5. Reassemble and Recheck

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications (usually around 80-100 lb-ft).
Reconnect the battery.
