EQUIPMENT Getting to the bottom of air brake system leaks Faulty fittings, unsuitable seals, and corrosion can make air brake system leaks a challenge for fleets. By Gregg Wartgow [ DIAGNOSTICS & REPAIR ] B 12 Fleet Maintenance | June 2021 rake systems continue to represent the top reason for roadside inspection violations in the U.S. In fact, according to data from the Commercial Vehicle Safety Alliance (CVSA) International Roadcheck that took place in September 2020, brake system failures accounted for 25 percent of all vehicle-related out-of-service violations. There is just no messing around when it comes to brake systems - especially air brake systems. Unfortunately, there are a lot of opportunities for problems to emerge. Technicians must remain on their toes, particularly with respect to system leaks. Redline Detection is a manufacturer of diagnostic leak detection equipment. According to Mark Hawkins, head of technical products for Redline Detection, air brake leaks are becoming an even bigger issue for some fleets. That is why the Technology & Maintenance Council (TMC) has set up a task force to help address the issue.
