Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the battery if necessary for safety.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel using a socket set.
2. Take off the brake caliper by loosening the caliper bolts.
3. Remove the brake rotor by unscrewing any retaining screws if present.
4. Inspect the rotor for warping using a micrometer; replace if warped beyond specifications (typically 0.002 inches).
5. Install new rotors, ensuring they are clean and free of debris.
6. Reattach the caliper and wheel, tightening bolts to manufacturer's torque specifications (check service manual for exact values).

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the brake pads from the caliper bracket.
2. Inspect for uneven wear; replace if worn below the minimum thickness (usually 3mm).
3. Apply brake grease to the back of the new pads to prevent noise.
4. Install the new brake pads in the caliper bracket.

4. Inspect Suspension Components

Sub-steps:
1. Conduct a visual inspection of the struts, shocks, and bushings.
2. Check for any signs of leaks or physical damage.
3. Replace any damaged components as necessary.

5. Wheel Alignment and Balance

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Ensure that both the alignment and wheel balancing are performed according to specifications.
