Lift the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Tools Required: Socket set, lug wrench
- Loosen the lug nuts slightly while the vehicle is on the ground.
- Lift the vehicle and remove the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Tools Required: Ratchet, socket set, brake pad spreader
- Remove the caliper bolts using the ratchet and socket.
- Carefully slide the caliper off the rotor.
- Remove the old brake pads from the caliper bracket.
- Check the pad thickness; if less than 3mm, replace them.
- Install new brake pads, ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Torque wrench, rotor puller (if necessary)
- Check the rotors for scoring or warping.
- If damaged, remove the old rotors by unscrewing the retaining screws if applicable.
- Install new rotors, ensuring to clean the surface with brake cleaner to remove any residue.
- Torque the rotor screws to the manufacturer’s specifications.
