Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and parked securely.
Disconnect the vehicle's battery for safety.

2. Inspect and Replace Brake Rotors

Remove Wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts with a socket set and take off the wheel.
Inspect Rotors:
- Check rotors for signs of warping or uneven wear.
- If warped beyond specifications (typically more than 0.002 inches), proceed to replace.
Remove Rotors:
- Unscrew the caliper bracket bolts and remove the caliper.
- Slide off the rotor from the hub.
Install New Rotors:
- Clean the hub surface with brake cleaner.
- Install the new rotor, ensuring it sits flush against the hub.
- Reattach the caliper and secure it with the bolts, applying the manufacturer-specified torque.

3. Inspect and Replace Brake Pads

Remove Old Pads:
- Remove the caliper as previously described.
- Slide out the old brake pads from the caliper bracket.
Install New Pads:
- Insert new brake pads into the caliper bracket, ensuring proper orientation.
- Reinstall the caliper over the new pads and secure it.

4. Check and Adjust Suspension Components

Inspect Components:
- Visually inspect control arms, bushings, and tie rods for wear or damage.
- Replace any worn components as necessary.

5. Tire Balance and Alignment

Balance Tires:
- Remove tires and take them to a tire shop for balancing.
Check Alignment:
- Have a professional perform a wheel alignment to ensure all wheels are set to the correct angles.
