Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, caliper tool, OBD-II scanner, brake cleaner.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid any electrical issues.

2. Raise the Vehicle

Use the jack to lift the vehicle at the designated jacking points.
Secure the vehicle with jack stands to ensure stability.

3. Remove Wheel

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

4. Inspect and Replace Brake Pads

Inspect: Check the brake pads for wear. Replace if they are less than 3mm thick.
Replace:
1. Remove the caliper bolts using a socket set.
2. Slide the caliper off the rotor.
3. Remove old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are correctly seated.
5. Reinstall the caliper over the new pads and tighten the caliper bolts to the specified torque (typically around 25-30 Nm).

5. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or warped, they should be replaced:
1. Remove the caliper bracket if necessary.
2. Slide the rotor off the hub.
3. Install the new rotor, ensuring it is properly aligned with the hub.
4. Reattach the caliper bracket and tighten bolts as specified.

6. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then tighten the lug nuts to the proper torque specification (typically around 100-110 Nm).

7. Final Checks

Reconnect the battery.
Pump the brake pedal to ensure proper brake engagement.
