Solution

1. Preparation

Gather necessary tools and parts (listed below).
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

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 the brake pads for uneven wear or damage.
If replacement is needed:
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 are properly seated.
5. Apply brake grease to the contact points of the pads to prevent squeaking.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are damaged:
1. Remove the caliper bracket by loosening the bolts.
2. Slide the rotor off the hub.
3. Install new rotors, ensuring they are clean and free of debris.
4. Reattach the caliper bracket and torque the bolts to the manufacturer's specifications.

5. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the specified torque value.
Reconnect the negative battery terminal.
