Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Brake Components

Brake Pads

Sub-steps:
- Remove the wheel using a socket set.
- Remove the caliper bolts with a socket wrench.
- Slide the caliper off the rotor and support it with a bungee cord (do not let it hang).
- Remove the old brake pads and inspect for wear.
- Install new brake pads, ensuring they are properly seated.

Brake Rotors

Sub-steps:
- Check the rotor thickness with a micrometer; replace if below specifications.
- If rotors are warped, remove them by unbolting from the hub assembly.
- Clean the hub surface before installing new rotors.
- Install new rotors and torque bolts to manufacturer specifications (usually around 80-100 ft-lbs).

3. Wheel Alignment and Balancing

Sub-steps:
- Mount the vehicle on a wheel alignment machine.
- Adjust alignment angles to manufacturer specifications.
- Balance the wheels if necessary, using a wheel balancer.

4. Suspension Inspection

Sub-steps:
- Visually inspect control arms, bushings, and struts for damage or wear.
- Replace any worn components, ensuring all fasteners are torqued to spec.
