Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Lug wrench
- Brake cleaner
- Torque wrench
- OBD-II scanner
Safety Warnings:
- Ensure the vehicle is on a flat surface and the parking brake is engaged.
- Allow brakes to cool before working on them.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the wheel using a lug wrench.
3. Inspect the brake pads for wear; replace if they are below the manufacturer's minimum thickness (typically around 3mm).
4. If replacing, remove the caliper bolts using a socket set, then carefully slide the caliper off the rotor.
5. Replace the old brake pads with new ones, ensuring proper orientation.
6. Reinstall the caliper and torque the bolts to the manufacturer’s specifications (usually around 30-40 lb-ft).

3. Inspect and Resurface or Replace Brake Rotors

Sub-steps:
1. Check rotors for warping using a run-out gauge; if warped beyond tolerance, replace or resurface them.
2. Clean the rotor surface with brake cleaner.
3. If replacing, remove the rotor by unbolting it from the hub.
4. Install the new rotor, ensuring it sits flush and is properly secured.

4. Check Suspension Components

Sub-steps:
1. Inspect control arms, tie rods, and bushings for wear or damage.
2. Replace any worn components as necessary.
3. Ensure that all fasteners are tightened to the specified torque values.

5. Wheel Alignment and Balancing

Sub-steps:
1. After reassembling everything, take the vehicle to a professional for wheel alignment and balancing.
2. Verify that the tires are balanced and properly inflated.
