Jimm 5/11/2012Definitely not - do NOT use copper tubing in place of steel brake tubing. The copper will not withstand the hydraulic pressure and the fluid will leak - perhaps suddenly - potentially putting yourself and others in danger.
Try the many on-line auto parts sources, such as; wwww.RockAuto.com or www.autopartswarehouse.com for the replacement parts. New brake lines made of the correct grade of steel are inexpensive when compared to the risk.
Gilbert Oliver 5/11/2012copper tubing is not recomended because of high pressure. You can buy the brake lines at the auto parts store but you need a tube bender to bend the tubing as you go also need to know how to use that tool. I suggest to practice with old brake line..
