A mechanic named Thomas created a viral TikTok video expressing skepticism about the accuracy of modern car technology. He pointed to his Chevrolet truck’s dashboard display showing 95% of its front brakes and 94% of its rear brakes still in good condition after 7,000 miles. Thomas questioned the reliability of the system, given his driving habits and truck setup, which he said would typically lead to more wear and tear. He also expressed doubt about the displayed MPG reading of 20 MPG, given the truck’s heavy load and city driving. Thomas believed that the brake pads would typically last around 50,000 to 60,000 miles, not 100,000 miles as displayed. The accuracy of modern brake wear sensors can vary depending on several factors, including driving habits, road conditions, and type of brake pads. While sensors can be helpful, regular physical inspections remain essential for safety and optimal performance. The video sparked debate among viewers, with some agreeing with Thomas while others shared their own experiences with Chevrolet truck brake pads.
