Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, caliper tool, torque wrench, OBD-II scanner.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical issues while working.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel using the lug wrench.
3. Inspect the brake pads for thickness; replace if worn below manufacturer specifications.
4. Remove the caliper bolts and slide the caliper off the rotor.
5. Remove the old brake pads and replace them with new ones, ensuring they are properly seated.
6. Reinstall the caliper and torque the bolts to manufacturer specifications.
7. Reattach the wheel and lower the vehicle.

3. Check and Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are warped, remove them by unbolting from the hub.
2. Measure rotor thickness with a micrometer; replace if below minimum specifications.
3. Install new rotors, ensuring they are properly aligned and bolted.
4. Reinstall the caliper over the new rotor.

4. Inspect Suspension Components

Sub-steps:
1. Visually inspect the control arms, bushings, and tie rods for signs of wear or damage.
2. Replace any worn components using appropriate tools and techniques.
3. Ensure all bolts are torqued to manufacturer specifications.

5. Wheel Alignment and Balancing

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Ensure that the alignment is within manufacturer specifications.
3. Balance the wheels if necessary to correct any vibration issues.
