Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and a flashlight.
Safety Warnings: Ensure the vehicle is on a flat surface and engage the parking brake before lifting the vehicle.

2. Brake Component Maintenance

Sub-steps:
1. Lift the vehicle and remove the wheel using a lug wrench.
2. Inspect brake pads for wear; replace if thickness is below the manufacturer's specifications.
3. Clean the brake components using brake cleaner to remove dust and debris.
4. Apply anti-squeal lubricant on the back of the brake pads and the contact points on the caliper.
5. Reassemble the wheel and torque the lug nuts to the manufacturer's specifications.

3. Suspension Inspection and Repair

Sub-steps:
1. Visually inspect all suspension components for visible wear or damage.
2. Check bushings for cracking or deterioration and replace if necessary.
3. Tighten any loose bolts or nuts on the suspension components to the manufacturer's torque specifications.

4. Drive Belt Inspection

Sub-steps:
1. Check the condition of the drive belt for cracks or signs of wear.
2. Adjust the tension of the belt or replace it if it is loose or damaged.
3. If the belt is in good condition, apply belt dressing to reduce squeaking.
