[QUOTE="Mugarolla, post: 1572165, member: 8481"] Exactly. The cable is under max tension the whole time the E-brake is applied. A weak or frayed cable can break at anytime while under max tension, not just when it being placed under max tension. I'll give you a quick example. I was stuck in traffic behind a semi that had its rear end stuck in a ditch. A tow truck hooked a cable from its boom to the rear of the trailer to raise it up and swing it out. According to Sober, the only time this cable would break is when tension is first applied. Incorrect. The tow truck lifted the rear of the trailer 2 feet off the ground. He let it sit for a few seconds to make sure it would hold before swinging it back onto the road. The cable snapped before he started swinging the trailer. The cable had lifted the trailer and held for over 4 seconds before it broke. Just like the E-brake cable. You can apply full tension to the cable and it may not break while applying tension. But a weak cable can break at anytime while under tension. The cable attached to the semi held under full tension for almost 4 seconds before breaking. [/QUOTE]
