6. Reassemble the caliper and wheel, tightening the bolts to the manufacturer's torque specifications.

3. Inspect and Resurface or Replace Brake Rotors

Sub-steps:
1. Remove the brake rotor after removing the caliper as described above.
2. Use a micrometer to measure the thickness of the rotor; if below the minimum specification, replace the rotor.
3. If resurfacing, ensure the rotor is evenly machined.
4. Reinstall the rotor and caliper, ensuring proper alignment.

4. Examine Suspension Components

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Inspect control arms, bushings, and tie rods for any signs of wear or damage.
3. Replace any damaged components with OEM or equivalent parts.
4. Recheck all fasteners and torque to specifications.

5. Wheel Alignment and Balance

Sub-steps:
1. Take the vehicle to a qualified alignment shop.
