Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Inspect Brake Pads and Rotors

Sub-steps:
- Remove the front wheels using a lug wrench.
- Inspect brake pads for thickness; replace if below 3mm.
- Measure rotor thickness with a micrometer; replace if below the minimum specified thickness.
- Use a dial indicator to check for rotor runout; if greater than 0.002 inches, resurface or replace the rotor.
Tools Required: Lug wrench, micrometer, dial indicator.

3. Wheel and Suspension Inspection

Sub-steps:
- Check wheel balance using a tire balancer; rebalance if necessary.
- Inspect suspension components (e.g., struts, control arms) for wear or damage; replace faulty parts.
- Perform a visual inspection of the alignment; adjust as needed.
Tools Required: Tire balancer, alignment tools.

4. Brake System Bleeding (if necessary)

Sub-steps:
- If brake fluid is low or contaminated, replace it.
- Use a brake bleeder kit to remove air from the brake lines: start from the furthest wheel from the master cylinder.
- Ensure the master cylinder is filled with the appropriate brake fluid type (DOT 3 or DOT 4).
Tools Required: Brake bleeder kit, brake fluid.
