I recently bought a set of Apex steel braided brake lines (http://www.apexbrakes.com) from Rennsport Auto Parts via an Ebay auction [url="http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=190343192615"]http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=190343192615[/url]
Last weekend, they were installed on an 1984 944 NA running in the 24 Hours of Lemons. At the six hour mark, both front brake lines failed catastrophically under heavy braking prior to the Karussel turn. Both lines blew out of their crimp fittings simultaneously while the car was travelling about 80 mph at the end of a straightaway. The rear brakes continued to work for just long enough for the driver to throw the car into the banking then out--spinning to a stop short of the wall.
I know nothing about the manufacturer or vendor. They claim that the lines meet DOT and SAE standards. I don't know of any other cases where this has happened. I can only write about our experience and let you draw your own conclusions before using this brand of brake line on your car.
