The Mueller-Kueps 1/4" Brake Line Straightener, No. 462 046, is designed to straighten 1/4” brake line when it's bent. Using 16 ball beared precision rolls, the tool removes bends out of the line, resulting in a straighter line while saving the technician time. The tool is easy to use and doesn't require additional tools. Simply feed the brake line through the tool, hold the line, and with the other hand move the tool back and forth. If the line is particularly bent, users might need to move the tool back and forth a couple times.
