The Mueller-Kueps Brake Line Straightener, No. 462 040, is designed to allow the user to straighten a brake line with 16 ball-beared precision rolls, after it has been rolled off a coil. It provides the user with a straight line to place onto the vehicle and will reduce the issues caused by a kinked brake line. Easy and quick to use, simply slide the tool onto the brake line far enough to have a handhold, then move the tool along the line. If kinked, simply move the tool up and down the line a couple of times to remove all kinks.
