Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety goggles, gloves.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged. Disconnect the battery before working on electronic components.

2. Remove Wheel

Loosen the lug nuts on the wheel using a lug wrench.
Use the jack to lift the vehicle and securely place it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor; do not let it hang by the brake line.
Remove the old brake pads from the caliper bracket.
Compare the old pads with new ones; install new pads ensuring they are oriented correctly.
If old pads are excessively worn, take note of any scoring on the rotor.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are damaged, remove them by unscrewing the rotor retaining screws (if equipped) and pulling the rotor off the hub.
Clean the hub surface with brake cleaner.
Install the new rotor, ensuring it fits flush against the hub.
Secure the rotor with retaining screws, if applicable.

5. Reassemble and Torque Components

Reposition the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque setting.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to fully tighten the lug nuts to the manufacturer's specifications.

6. Final Checks

Pump the brake pedal several times to seat the new pads properly.
Inspect the brake fluid level and add fluid if necessary.
