Keeping air lines and fittings free of contaminants is crucial for the proper functioning of the brake system. Contaminants such as dirt, moisture, oil, or debris can enter the air supply, leading to several problems. These can include blockages in the air lines, corrosion of the fittings, and malfunctions of components in the brake system, which may ultimately lead to air leaks.

When air lines or fittings become contaminated, it can disrupt the flow of compressed air necessary for activating the braking mechanisms. This disruption can impair responsiveness and reduce the overall effectiveness of the brakes, posing safety hazards. Therefore, maintaining cleanliness in the air supply system is essential to ensure reliable brake performance and to prevent potential failure of the entire braking system.

Ensuring that components are free of contaminants is a fundamental maintenance practice that supports the safe and efficient operation of vehicles equipped with air brake systems.
