Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a flat surface.
Engage the parking brake and wear safety glasses and gloves.

2. Lift Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake assembly.
Tools required: Jack, jack stands, lug wrench.

3. Inspect Brake Components

Check the brake pads for wear; replace if less than 3mm thick.
Inspect the rotors for grooves or warping; replace if necessary.
Tools required: Brake pad gauge, caliper tool.

4. Replace Brake Pads (if worn)

Remove the caliper bolts with a socket wrench and carefully lift the caliper off the rotor.
Replace old brake pads with new ones, ensuring they are correctly seated.
Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically 20-25 ft-lbs).

5. Replace Rotors (if damaged)

Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
Install new rotors, ensuring they are clean and free of any protective coatings.
Torque any retaining screws to manufacturer specifications.

6. Final Assembly

Reinstall the wheel and torque the lug nuts to the specified value (usually 80-100 ft-lbs).
Lower the vehicle from the jack stands and remove the jack.
