Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, turn off the ignition, and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Inspect Brake Pads and Rotors

Sub-steps:
- Remove the wheel using a socket set.
- Inspect the brake pads for thickness; replace if below manufacturer's specifications.
- Check the rotors for warping using a dial indicator or by visually inspecting for grooves and uneven surfaces.
- If warped, proceed to replace rotors.

3. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
- Remove the caliper by unscrewing the caliper bolts and lifting it away from the rotor.
- Remove the brake pads from the caliper bracket.
- Install new brake pads into the bracket.
- If replacing rotors, remove the old rotor and install the new rotor, ensuring it is seated correctly.
- Reattach the caliper over the new rotor and pads, tightening the caliper bolts to the manufacturer's torque specifications (usually around 25-35 ft-lbs).

4. Wheel Alignment and Balancing

Sub-steps:
- Take the vehicle to a professional alignment shop.
- Request a four-wheel alignment and balancing service to ensure that all wheels are aligned correctly and balanced.

5. Inspect Suspension Components

Sub-steps:
- Visually inspect suspension components, including control arms, bushings, and struts for any signs of wear or damage.
- Replace any damaged suspension components as needed.
