![]() Truckers must know how to check slack adjusters regularly, especially before setting out on long hauls. “Many accidents occur because commercial drivers fail to follow basic safety procedures. However, critics claim that automatic slack adjusters may adjust incorrectly, causing brakes to fail. Automatic slack adjusters, on the other hand, adjust themselves, depending on the distance between the brake drum and the brake shoe. Manual slack adjusters must be regularly adjusted because drivers can’t always know when the brake shoes have worn down, meaning their brakes may be inadequate or not performing as they should. The debate centers around manual slack adjusters versus automatic slack adjusters. While the purpose of slack adjusters in the trucking industry is undeniable, there remains a controversy around their use. The Controversy Around Slack Adjusters In The Trucking Industry ![]() Therefore, air brakes are the standard brakes for semi-trucks. Semi-trailer trucks are heavy-duty vehicles that require advanced braking systems to support their weight and ensure the safety of the driver and other road users. The FMCSA has rigid safety regulations that all commercial vehicles must adhere to, including slack adjusters. Do All Semi Trucks Have Slack Adjusters?Īll commercial trucks with air brakes should have slack adjusters. In addition, it’s vital to keep slack adjusters clean and free of debris, which could cause wear and tear. The slack adjuster should sit perpendicular to the push rod. Trucks with air brakes, slack adjusters can be found on the push rod connected to the brake chamber. Slack adjusters are located on the rear axle in-between the brake shoes. Where Are The Slack Adjusters On A Truck? A slack adjuster that’s out of adjustment can cause brakes to fail, meaning a driver’s license could be at risk, not to mention the safety of all road users. CDL drivers should know how slack adjusters work, how to check them, and how to adjust them. What Are The Slack Adjusters CDL?Ĭommercial driver’s license (CDL) holders should be aware of slack adjusters because they are an essential component of their vehicles’ braking system. As a result, the Federal Motor Carrier Safety Administration (FMCSA) has strict maintenance requirements for commercial vehicles, including slack adjusters. Unfortunately, many accidents on our roads are caused by poorly maintained brakes. If a slack adjuster isn’t functioning correctly, it can cause brakes to fail, leading to accidents and fatalities. Slack adjusters are designed to automatically adjust the braking system’s slack to ensure optimal braking performance. When you release the brakes, the slack adjuster ensures that the brake shoes return to their default position. ![]() When you apply the brakes, the slack adjuster reacts by expanding the brake shoes toward the brake drum, increasing the braking force. Its main purpose is to maintain an appropriate gap, or “slack,” between the brake shoe and the drum or rotor. What Is The Purpose Of A Slack Adjuster?Ī slack adjuster is a critical part of the braking system found in heavy-duty commercial vehicles such as 18-wheelers. In this article, we will delve deeper into the meaning of slack adjusters, how they work, and why they are so essential for the trucking industry. ![]() However, despite its importance, slack adjusters are somewhat controversial in the industry. The slack adjuster is a vital component of the braking system that ensures proper braking function. That’s where the slack adjuster comes in. ![]() It’s a scary thought to think of a huge truck without brakes, but it happens more often than you would think. The brakes are the only thing that keeps a moving truck from colliding with other vehicles and pedestrians on the road. When it comes to the trucking industry, brake maintenance is one of the most critical aspects that should not be overlooked. ![]()
