Common Brake Problems in Heavy-Duty Trucks & How to Fix Them

Brakes are one of the most critical safety features in heavy-duty trucks. Properly functioning brakes can mean the difference between a safe trip and a catastrophic accident. However, common brake problems can occur, leading to safety risks and costly repairs. In this article, we will discuss common brake problems in heavy-duty trucks and how to fix them.

Improper loading

Improper loading can cause all sorts of issues, including brake problems. When a truck is loaded incorrectly, it can affect the weight distribution, making it harder to stop the vehicle. To prevent this, ensure that your truck is loaded correctly, adhering to the weight distribution guidelines recommended by the manufacturer.

Improper maintenance

Brakes, like many other aspects of a heavy-duty truck, need to be constantly maintained to ensure they are working as designed. Failure to maintain your brakes can lead to serious problems, including brake failure. Regularly inspect your brakes for signs of wear and tear, such as worn brake pads or corroded brake lines. Replace worn or damaged parts promptly to avoid further damage.

Over-Braking

Over-braking can also cause brake problems in heavy-duty trucks. Drivers should avoid overtaxing the braking system by braking needlessly or using excessive force. This can cause the brakes to overheat, leading to brake fade or other brake-related issues.

Brake fade

Brake fade occurs when drivers inadvertently overheat the brake drums by over-braking or over-pumping the brakes. This can cause the brakes to lose their stopping power, leading to a safety risk. To prevent brake fade, use short, hard, intermittent brake applications instead of holding the brakes for long periods of time. This allows the brakes to cool between applications, preventing overheating.

Brake lock

A brake lock occurs when the brake shoe on the truck becomes stuck. Signs of this include sluggish acceleration, almost like the truck is being held back. This is because the shoe is struggling to release itself after being engaged. To prevent brake lock, regularly inspect your brakes for signs of wear and tear, such as worn brake shoes or corroded brake lines. Replace worn or damaged parts promptly to avoid further damage.

Damaged airline 

Due to its air system, brakes can become damaged when certain parts of the truck’s airline itself are either punctured, cracked, or broken. This means the air is no longer being pressurized properly, leading to ineffective braking. To prevent this, regularly inspect your airline for signs of damage, such as cracks or punctures. Replace any damaged parts promptly to ensure that your braking system is working correctly.

Final words

Brake problems can be a safety risk and can result in costly repairs. Improper loading, improper maintenance, over-braking, brake fade, brake lock, and damaged airline are some of the common brake problems in heavy-duty trucks. To prevent these issues, ensure that your truck is loaded correctly, maintain your brakes properly, avoid over-braking, use short, hard, intermittent brake applications, and regularly inspect your brakes and airline for signs of wear and tear.
