I recently had to replace the brake line in our T3. Some foolish backyard DIY put a holesaw through the very well hidden line while fitting a table base...Me My non-VW mech installed copper brake lines, at great expence. Ive since spoken to someone who experienced a complete brake failure due to the copper line used in his FJ and suggested I have them replaced to steel or s/s ASAP. Im now very concerned about the safety of the braking system. Wadda reakon KC. Any thoughts would be greatly appreciated.
