Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Remove Caliper:
- Use a socket set to remove caliper mounting bolts.
- Carefully slide the caliper off the rotor.
Check Brake Pads:
- Inspect pads for wear; if worn down to metal, replace them.
- If replacing, use new pads that are compatible with the model.
Install New Brake Pads:
- Insert new pads into the caliper bracket.

4. Inspect and Replace Rotors (if necessary)

Check Rotors:
- Measure rotor thickness and look for scoring or warping; if damaged, replace.
Remove Rotor:
- If needed, remove the rotor by unscrewing any retaining screws or clips.
Install New Rotor:
- Place the new rotor onto the hub and secure it.

5. Reassemble Brake Components

Reattach Caliper:
- Slide the caliper over the new pads and rotor.
- Tighten the caliper mounting bolts to manufacturer specifications.
Reinstall Wheel:
- Place the wheel back onto the hub and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the specified torque value.

6. Test Brakes

Reconnect the battery and pump the brake pedal to ensure proper pressure.
Check for any abnormal noises or issues during a short test drive.
