Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Safely park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if needed for electrical safety.

2. Lift the Vehicle

Use the jack to lift the vehicle and secure it on jack stands.
Remove the wheel using the lug wrench.

3. Remove Brake Components

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the brake rotor. Support it with a bungee cord to avoid straining the brake line.
Remove the brake pads from the caliper bracket.

4. Inspect Rotors

Inspect the brake rotors for grooves, cracks, or significant wear.
If damaged, replace the rotors. If they are within specifications, proceed to clean them with brake cleaner.

5. Install New Brake Pads

Apply brake grease to the back of the new pads to prevent noise.
Install the new brake pads in the caliper bracket.

6. Reassemble

Reposition the caliper over the new pads and secure it with the caliper bolts. Torque to the manufacturer's specifications.
Reinstall the wheel and lower the vehicle off the jack stands.

7. Final Checks

Reconnect the battery if disconnected.
Pump the brake pedal several times to seat the pads.
Check brake fluid level and top off if necessary.
