Clark: How fleets can put a stop to OOS brake violations

The results are in from the May 2025 Commercial Vehicle Safety Alliance (CVSA) International Roadcheck, and once again, brake-related issues top the list of out-of-service (OOS) violations. Despite ongoing efforts across the industry, the numbers remain stubbornly high.

Out of more than 56,000 inspections conducted across North America, 24.4% of OOS violations were due to brake systems, with another 20% attributed to defective brakes. In the U.S. alone, the figures are only slightly better: 24% for brake systems and 15% for defective brakes.

These statistics are not an anomaly; they’re part of a persistent trend. Brake system violations have consistently led the pack over the past eight years:

• 2018: 28.4%
• 2019: 28%
• 2020: 25.8%
• 2021: 26.5%
• 2022: 25%
• 2023: 25.4%
• 2024: 25%

While there has been modest improvement, it’s clear that more needs to be done. In today’s climate of economic uncertainty, every truck on the road must be operating at peak efficiency, and that starts with safe, compliant braking systems.

Preventive and predictive maintenance: Keeping truck brakes compliant and road-ready

With over-the-road (OTR) Class 8 trucks averaging between 100,000 and 150,000 miles annually, it’s no surprise that brakes endure significant wear and tear, especially in stop-and-go traffic on congested highways. That’s why both preventive maintenance and predictive maintenance are essential.

A preventive maintenance program should include the following:

• Inspecting brake pads and linings for wear, cracks, or defects
• Flushing and replacing brake fluid
• Checking for and repairing air leaks
• Replacing damaged or missing components

Predictive maintenance, powered by modern telematics and sensor technology, takes things a step further. These systems monitor brake performance in real time, allowing fleets to detect and address issues before they escalate into costly breakdowns or OOS violations. Proactive repairs are more cost-effective while also increasing safety on the road.

Driver monitoring: Spotting early brake issues to reduce OOS violations

Drivers play a critical role in brake safety. They’re often the first to notice signs of trouble, such as unusual noises, reduced braking power, or dashboard alerts. That’s why driver training should include how to recognize early warning signs of brake issues.

Fleets should also analyze patterns: If certain drivers consistently report brake problems, it may indicate a need for additional training or a closer look at driving habits that contribute to premature wear.

Brake safety strategies: Minimizing costs, downtime, and compliance risks

Brake violations aren’t just a regulatory headache; they’re a safety risk and a financial liability. Reducing OOS violations requires a multi-pronged approach: rigorous maintenance schedules, smart use of predictive technologies, and well-trained drivers who know what to look for.

By investing in these areas, fleets can not only improve safety and compliance but also reduce downtime, avoid costly repairs, and extend the life of their equipment. In a business where uptime is everything, staying ahead of brake issues isn’t just smart; it’s essential.
