Use a socket set to loosen and remove the lug nuts.
Take off the wheel to access the brake components.

4. Remove Brake Caliper

Locate the caliper mounting bolts and remove them using a socket wrench.
Slide the caliper off the brake rotor and support it using a bungee cord or rope to avoid straining the brake line.

5. Inspect and Replace Brake Pads

Check the thickness of the brake pads; replace if they are less than 3mm.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are oriented correctly.

6. Reassemble Components

Reinstall the brake caliper over the new pads.
Tighten the caliper mounting bolts to the manufacturer's torque specifications.
Reattach the wheel and tighten the lug nuts in a crisscross pattern.

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.

8. Test Brakes

Pump the brake pedal several times to seat the new pads.
Perform a test drive to ensure brakes function properly.
