Solution

1. Preparation

Gather necessary tools and replacement parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical accidents.

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 to access the brake components.

3. Inspect Brake Components

Brake Pads: Remove the brake caliper by unbolting it with the appropriate socket. Check the thickness of the brake pads; if they are below 3mm, replace them.
Brake Rotors: Examine the rotors for any signs of scoring or warping. If damaged, replace the rotors. Use a micrometer to check the thickness of the rotor; it should meet manufacturer specifications.

4. Replace Parts as Necessary

If brake pads are worn, install new brake pads. Ensure they are aligned properly in the caliper bracket.
If rotors are warped, replace them with new ones, ensuring they are torqued to the manufacturer’s specifications (usually around 80-90 ft-lbs).

5. Reassemble Components

Reattach the brake caliper and ensure all bolts are tightened to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.

6. Final Checks

Reconnect the battery and check the brake fluid level, topping off if necessary.
Test the brake pedal feel and ensure the brake system is functioning properly.
