Check tire pressure and ensure it meets manufacturer recommendations.
If tires are worn or damaged, replace them with new ones, ensuring they are properly balanced and aligned.
Inspect for any foreign objects lodged in the tread and remove them if necessary.

4. Assess and Replace Brake Components

Tools Required: Jack, jack stands, lug wrench, brake cleaner, new brake parts
Remove the wheel to access the brake components.
Inspect brake pads and rotors for signs of wear or overheating. Replace as necessary.
Clean the brake assembly with brake cleaner and ensure all components move freely without binding.
