Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the front wheels using a socket set.
2. Unbolt the brake caliper and secure it using a bungee cord to avoid stress on the brake line.
3. Remove the old brake pads and set them aside.
4. Remove the brake rotor by unbolting it from the hub assembly.
5. Install new brake rotors, ensuring they are properly seated.
6. Reinstall the brake caliper and pads, ensuring proper alignment.
7. Torque caliper bolts to manufacturer specifications (typically around 25-30 Nm).

3. Wheel Alignment and Suspension Inspection

Sub-steps:
1. Inspect the control arms, tie rods, and bushings for wear or damage.
2. Replace any worn components as needed.
3. Perform a wheel alignment using an alignment machine to ensure proper angles.

4. Wheel Balancing

Sub-steps:
1. Mount the wheels on a wheel balancing machine.
2. Identify any imbalance and add weights to achieve balance.
3. Reinstall balanced wheels back onto the vehicle.
