Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and set the parking brake.
Disconnect the negative terminal of the battery to ensure safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Elevate the vehicle with a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Inspect Pads: Examine the brake pads for uneven wear or damage.
Remove Pads: Unbolt the caliper using a socket set and slide it off the rotor. Remove the old brake pads from the caliper bracket.
Install New Pads: Place new brake pads into the caliper bracket, ensuring they are positioned correctly.

4. Inspect and Resurface Brake Rotors

Check Rotor Condition: If the rotors are worn or scored, they may need to be resurfaced or replaced.
Resurface or Replace: If resurfacing, mount the rotors on a brake lathe; otherwise, remove the old rotor and install a new one using the appropriate torque specifications (usually 75-100 ft-lbs).

5. Reassemble Components

Reattach the caliper over the new pads and rotor. Tighten the caliper bolts to the manufacturer's torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern to the specified torque.

6. Final Checks

Reconnect the negative terminal of the battery.
Pump the brake pedal several times to seat the brake pads properly.
