3. Check and Replace Brake Components

Tools Required: Jack, jack stands, lug wrench, brake caliper tool
Sub-steps:
1. Safely lift the vehicle and remove the wheels.
2. Inspect brake pads for thickness; replace if they are worn down.
3. Check brake rotors for scoring; replace if necessary.
4. Reassemble the brake components and wheels, ensuring proper torque specifications are followed.

4. Inspect and Repair Tire Issues

Tools Required: Tire pressure gauge, air compressor
Sub-steps:
1. Check tire pressure; inflate to the manufacturer's recommended PSI.
2. Inspect for any debris lodged in the tires or sidewall bulges.
3. Rotate or replace tires if they show uneven wear or damage.
