Solution

1. Preparation

Gather tools: jack and jack stands, lug wrench, torque wrench, brake cleaner, micrometer, and alignment tools.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on the electrical components of the braking system.

2. Inspect and Replace Brake Rotors

Lift the Vehicle:
- Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the Wheel:
- Use a lug wrench to remove the lug nuts and take off the wheel.
Inspect Brake Components:
- Check the brake pads for wear and the caliper for any leaks.
Measure Rotor Thickness:
- Use a micrometer to measure the thickness of the rotor. If below minimum specifications, proceed to replace.
Remove Brake Caliper:
- Use the appropriate socket to unbolt the caliper and suspend it without straining the brake line.
Remove the Rotor:
- Unbolt the rotor from the hub if necessary and remove it.
Install New Rotor:
- Place the new rotor on the hub and secure it with bolts as per manufacturer specifications.
Reinstall Caliper and Pads:
- Install new brake pads if they are worn, then reinstall the caliper and torque to specifications.

3. Wheel Alignment and Balancing

Check Wheel Alignment:
- After replacing the rotors, check and adjust the wheel alignment using alignment equipment.
Balance the Wheels:
- Ensure tires are balanced properly. If necessary, take to a shop for professional balancing.
