Was in So. Utah last week and drove down the Burr Trail out of Bolder Ut. to Lake Powell. Went down "Water pocket fold", a 1000 ft. drop in less than a mile. Switch backs like Lombard street on steroids. Got the bottom and started across the desert and NO BREAKS. Half mile earlier and I'd be dead. So..... It's a stock 84' K5 10 bolt front and back. Everything was so hot it boiled water for a half an hour. Things worked fine after it cooled down but I don't want this to happen again. What sould I do?
