Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, lug wrench, OBD-II scanner, dial indicator, torque wrench.
Ensure the vehicle is on a flat surface and the parking brake is engaged. Disconnect the battery if working with any electrical components.

2. Inspect Brake Components

Sub-steps:
1. Remove the front wheels using the lug wrench.
2. Inspect brake pads for uneven wear; replace if necessary.
3. Measure rotor thickness with a micrometer; replace if worn below the manufacturer’s specification.
4. Check for any scoring or warping on the rotor using a dial indicator.

3. Replace Rotors and Pads (if necessary)

Sub-steps:
1. Remove the caliper bolts and carefully detach the caliper from the rotor.
2. Remove the old rotor by unscrewing the retaining screws (if present).
3. Clean the hub surface to ensure proper contact with the new rotor.
4. Install the new rotor and tighten the retaining screws to the manufacturer's specifications.
5. Install new brake pads into the caliper bracket.
6. Reattach the caliper and secure with bolts; torque to manufacturer specifications.

4. Inspect and Repair Suspension

Sub-steps:
1. Check all suspension components for signs of wear or damage, focusing on control arms, bushings, and tie rods.
2. Replace any worn or damaged components as needed.
3. Ensure all connections are tight and properly torqued.

5. Wheel Alignment and Balancing

Sub-steps:
1. After reassembling the brakes and wheels, take the vehicle to a professional for a wheel alignment and balancing.
2. Verify that the alignment settings match the manufacturer’s specifications.
