Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the battery if working on electrical components.

2. Brake Inspection and Replacement (if applicable)

Remove the Wheel:
- Use a lug wrench to loosen the lug nuts.
- Raise the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts and take off the wheel.
Inspect Brake Components:
- Check the brake pads for thickness; replace if worn down.
- Inspect the rotors for scoring or warping; replace if necessary.
Replace Brake Pads:
- If new pads are needed, remove the caliper by unscrewing the caliper bolts.
- Slide out the old pads and install the new pads in the caliper bracket.
- Reinstall the caliper and torque the bolts to the manufacturer's specifications.

3. Suspension Component Inspection and Repair (if applicable)

Visual Inspection:
- Check all suspension components for wear, particularly bushings and joints.
- Look for any signs of leaking fluids from shocks or struts.
Tighten or Replace Parts:
- Tighten any loose bolts or nuts found during the inspection.
- Replace any worn bushings or struts as necessary.

4. Drive Belt Inspection and Replacement (if applicable)

Inspect Drive Belts:
- Check for cracks or fraying on the belts.
Replace Belts:
- If damaged, loosen the tensioner and remove the old belt.
- Install the new belt following the routing diagram, ensuring proper tension.
