Check your break-away brake cable

Mine fell apart in my hands. It looks like stainless with a plastic coating but I guess it is galvanized or plain steel cable. The plastic cover was not UV stabilized and cracked, letting water in and rust followed. I tried to post a picture but got a file extension error.

And when you are replacing the break away cable make sure that extended it is longer than the safety chains.
