Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely raise it using a jack and jack stands.
Disconnect the battery to prevent any electrical issues during repair.

2. Inspect and Replace Brake Rotors

Sub-steps:
- Remove the wheel using a lug wrench.
- Take off the brake caliper by unbolting it and secure it with a bungee cord to avoid stress on the brake line.
- Remove the brake pads from the caliper bracket.
- Measure the rotor thickness using a micrometer; if below manufacturer specifications or warped, proceed to replace.
- Remove the rotor by unbolting it from the hub.
- Install new rotors, ensuring they are torqued to manufacturer specifications (usually around 100-120 ft-lbs).

3. Inspect and Replace Brake Pads

Sub-steps:
- Check the condition of the brake pads; replace if worn unevenly or below the minimum thickness.
- Install new brake pads, ensuring they are properly seated in the caliper bracket.
- Reinstall the caliper over the new pads and torque bolts to manufacturer specifications (typically 20-30 ft-lbs).

4. Inspect Suspension Components

Sub-steps:
- Visually check control arms and bushings for cracks or excessive wear.
- Replace any worn suspension components as necessary, following specific removal and installation procedures.

5. Reassemble and Test

Sub-steps:
- Reinstall the wheel and torque lug nuts to manufacturer specifications (usually 80-100 ft-lbs).
- Reconnect the battery.
- Lower the vehicle and perform a test drive to check for vibrations.
