Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface, and engage the parking brake.
Safety: Wear safety glasses and gloves.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Unbolt and remove the caliper from the rotor.
3. Inspect the brake pads for thickness; replace if below manufacturer's specifications.
4. Install new brake pads, ensuring they are properly aligned.
5. Reattach the caliper and torque the bolts to the manufacturer's specification.

3. Check and Resurface or Replace Brake Rotors

Sub-steps:
1. Remove the rotor from the hub by unbolting it from the wheel assembly.
2. Use a dial indicator to measure rotor runout; if warped, either resurface or replace the rotor.
3. Clean the hub surface to ensure proper contact with the rotor.
4. Install the rotor and torque the bolts to the specified value.

4. Inspect Suspension Components

Sub-steps:
1. Visually inspect control arms, ball joints, and bushings for wear or damage.
2. Replace any worn components with OEM parts.
3. Ensure all mounting points are secure and torqued to specifications.

5. Tire Inspection

Sub-steps:
1. Inspect tires for uneven wear or damage.
2. Rotate or replace tires as necessary.
3. Balance tires if they have been removed.
