What might be a consequence of improperly using a tubing wrench?

Using a tubing wrench improperly can lead to damaging the brake line. Tubing wrenches are specifically designed to securely grip and turn the fittings without rounding off the edges, which can happen with other types of wrenches. If the wrench is misused—for example, applying too much force or using the wrong size—it can deform or crush the tubing. This damage can create leaks or weaken the structural integrity of the brake line, leading to potentially dangerous situations while driving. Proper use of the correct tool ensures that the fittings are handled appropriately, maintaining the safety and functionality of the braking system.
