Wear safety glasses and gloves for protection.

2. Lift Vehicle

Use a jack to lift the front of the vehicle and secure with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Components

a. Inspect Brake Rotors

Sub-steps:
- Visually inspect rotors for signs of warping or scoring.
- Use a dial indicator to measure rotor runout; if it exceeds manufacturer's specifications, replace the rotors.

b. Replace Brake Rotors (if necessary)

Sub-steps:
- Unbolt the caliper and bracket from the rotor.
- Remove the old rotor and clean the hub surface.
- Install the new rotor, ensuring it is seated properly.
- Reattach the caliper and bracket, torque to manufacturer's specifications.

c. Inspect Brake Pads

Sub-steps:
- Check for sufficient pad thickness (at least 3mm).
- Look for uneven wear patterns; replace if necessary.

d. Replace Brake Pads (if necessary)

Sub-steps:
- Remove the caliper bolts and slide the caliper off the pads.
- Remove the old pads and install new ones, ensuring they are properly aligned.
- Reinstall the caliper, torque bolts to specifications.

4. Inspect and Replace Suspension Components (if necessary)

Sub-steps:
- Check control arms and bushings for signs of wear or damage.
