When you’re behind the wheel of a fully loaded semi-truck weighing up to 80,000 pounds, there’s one thing you absolutely can’t afford to second-guess: your brakes. A dependable braking system is the difference between a safe stop and a catastrophic accident. In the heavy-duty trucking industry, air brakes are the gold standard — a proven technology that delivers consistent stopping power, built-in safety features, and the durability to withstand thousands of miles in the most punishing conditions.
But even the most robust air brake system isn’t “set it and forget it.” Every driver and fleet maintenance team needs to understand how these systems work, how to recognize trouble before it escalates, and when it’s time to replace key components.
