Prolonged exposure to cold weather can cause air brake lines on construction equipment, buses and other heavy duty vehicles to freeze. Frozen air brake lines present potentially serious safety issues for the user of the equipment and those around him. Fortunately, there's a simple way to prevent the problem.
Buy an air brake antifreeze solution from an auto supply store or online.
Remove the fitting from your evaporation reservoir tank.
Pour in the recommended amount of air brake antifreeze. This will vary depending upon the product used.
Replace the fitting onto the tank.
