3. Remove Wheel

Using a socket set, remove the lug nuts and take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Check Brake Pads:
- Remove the caliper bolts to access the brake pads.
- Inspect pads for thickness; replace if below 3mm.
Replacement:
- Remove the old pads and install new pads. Ensure they are properly seated.

5. Inspect and Replace Brake Rotors (if necessary)

Check Rotors:
- Inspect the rotors for scoring or warping.
Replacement:
- If damaged, remove the caliper and the rotor using the appropriate socket.
- Install new rotors, ensuring they are torqued to the manufacturer's specifications.

6. Reassemble Brake Components

Reattach the caliper and torque the bolts to the manufacturer's specifications.
Reinstall the wheel and torque the lug nuts in a crisscross pattern.
