Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench, and OBD-II scanner.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Remove Wheel

Loosen lug nuts with a lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect: Check the brake pads for uneven wear or thickness less than 3mm.
Replace:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they sit correctly in the bracket.
5. Apply brake grease to the back of the pads to prevent noise.

4. Inspect and Replace Brake Rotors

Inspect: Check the rotor surface for scoring or excessive wear.
Replace:
1. If replacing, remove the caliper bracket bolts and remove the bracket.
2. Slide the rotor off the hub.
3. Install the new rotor, ensuring it sits flush against the hub.
4. Reinstall the caliper bracket and torque the bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the caliper and torque the bolts to specifications.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts in a crisscross pattern to the specified value.
Reconnect the battery.
