Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and is securely lifted with jack stands.
Disconnect the battery for safety.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspection: Check the thickness of the brake pads. If they are below 3mm, replacement is necessary.
Removal:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the brake rotor.
- Support the caliper with a bungee cord or similar to avoid straining the brake line.
Replacement:
- Remove the worn brake pads from the caliper bracket.
- Install new brake pads, ensuring they are positioned correctly.
- Reattach the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (typically around 23-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Inspection: Check rotors for scoring or warping using a dial indicator.
Replacement:
- If the rotors are damaged, remove them by unscrewing the retaining screws (if applicable) and sliding them off the hub.
- Install new rotors, ensuring they are clean and free of oil.
- Reinstall the caliper assembly.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque (around 100-120 ft-lbs).
Reconnect the battery.
