Solution

1. Preparation

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

2. Raise and Secure the Vehicle

Loosen the lug nuts on the front wheels slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the front wheels by fully unscrewing the lug nuts.

3. Remove Brake Components

Remove the caliper by unscrewing the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor; support it using a bungee cord or a suitable hook to avoid straining the brake line.
Take off the old brake pads from the caliper bracket.
Remove the rotor if necessary by unscrewing any retaining screws and sliding it off the hub.

4. Inspect and Replace

Inspect the brake rotor for damage; if it is severely scored or warped, it may need to be replaced or resurfaced.
Clean the rotor surface with brake cleaner to remove any debris or oils.
Install new brake pads into the caliper bracket, ensuring they are oriented correctly.
If the rotor was removed, slide the new or resurfaced rotor onto the hub.

5. Reassemble Brake Components

Reattach the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer's specified torque (usually around 20-30 ft-lbs).
Reinstall the wheels and hand-tighten the lug nuts.

6. Lower the Vehicle and Finalize

Carefully remove the jack stands and lower the vehicle back to the ground.
Once on the ground, fully tighten the lug nuts in a star pattern to the specified torque (typically around 76-80 ft-lbs).
