- Raise the vehicle using the jack and secure it with jack stands.

2. Remove Wheel

Instructions:
- Completely remove the lug nuts and take off the wheel.
- Place the wheel in a safe location.

3. Inspect Brake Components

Instructions:
- Visually inspect the brake pads; if they are worn down to less than 3mm, replace them.
- Check the rotors for grooves or excessive wear; if damaged, they may need to be resurfaced or replaced.
- Ensure calipers are not sticking and are functioning properly.

4. Replace Brake Pads (if necessary)

Instructions:
- Remove the caliper bolts using a socket set and lift the caliper off the rotor.
- Remove old brake pads from the caliper bracket.
- Compress the caliper piston using a C-clamp or brake tool.
- Install new brake pads in the caliper bracket.
- Reattach the caliper over the new pads and secure with bolts to manufacturer specifications.

5. Replace Rotors (if necessary)

Instructions:
- Remove the old rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
- Clean the hub surface with brake cleaner to remove any debris or rust.
- Install the new rotor, ensuring it sits flush against the hub.

6. Reassemble and Lower Vehicle

Instructions:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle to the ground and fully tighten the lug nuts to the manufacturer’s torque specification.
