Diagnosing the Causes of Locked Up Trailer Brakes on 7

Imagine cruising down the highway, towing your valuable cargo on your trusty Big Tex trailer, when suddenly you feel a jarring resistance. Your trailer brakes have locked up. This scenario is not only inconvenient but can also be dangerous, potentially causing damage to your trailer, tow vehicle, and even leading to accidents. Understanding why Big Tex trailer brakes lock up and how to address this issue is crucial for safe and efficient towing.

Brake lock-up on a Big Tex trailer, or any trailer for that matter, can stem from several issues ranging from simple maintenance oversights to more complex mechanical failures. From a stuck brake caliper to a malfunctioning breakaway system, the causes can be varied. This article will delve into the common reasons behind Big Tex trailer brake lock-ups, equipping you with the knowledge to diagnose and potentially fix the problem, ensuring a smoother, safer towing experience.

While Big Tex trailers are renowned for their robust construction and reliability, like any mechanical system, the brakes can experience issues. Regular maintenance is key to preventing lock-ups. Factors such as corrosion, worn brake components, and improper brake adjustments can all contribute to this problem. Understanding these potential issues is the first step in mitigating the risks associated with Big Tex trailer brake lock-up.

One of the most common reasons for Big Tex trailer brakes locking up is a malfunctioning breakaway system. This crucial safety feature is designed to engage the trailer brakes if the trailer becomes detached from the tow vehicle. However, a faulty breakaway switch, a corroded cable, or a discharged battery can inadvertently activate the system, resulting in an unexpected and potentially dangerous brake lock-up. Regularly inspecting and testing your breakaway system is paramount for preventing this issue.

Another common culprit behind Big Tex trailer brake lock-up is a problem with the brake lines. Air in the lines, a kinked hose, or a leak can disrupt the hydraulic pressure needed to properly engage and release the brakes. This can lead to uneven braking, and in some cases, complete lock-up. Properly bleeding the brake lines and regularly inspecting for leaks and damage are essential preventative measures.

Troubleshooting a Big Tex trailer brake lock-up often involves checking the breakaway system, inspecting the brake lines for leaks or kinks, and examining the brake drums and components for signs of wear or damage. If you're not comfortable performing these checks yourself, consult a qualified trailer mechanic.

One simple example of a Big Tex trailer brake locking up is when the breakaway cable is accidentally pulled. This immediately engages the brakes, bringing the trailer to a halt. While this is the intended function of the breakaway system, an accidental activation can be startling and inconvenient.
