What do you mean when you said the cam "rotated"? Do you mean it cammed over or what? If this is the case, it is just plain old sloppy maintenance. Your linings are too thin and your drum is worn out and and the cam bushings were probably worn. If you ran an red light going 35 miles per hour, that means you were just plain going too fast for the piece of junk you were driving. Did the truck have automatic slack adjusters? If so, did anyone ever grease them and make sure they worked? If not, did anyone ever adjust the brakes? If you don't have automatic slack adjusters, they don't adjust themselves. I doubt that a truck has left the factory in the last 25 years without an air dryer installed in the installed. But air dryers need maintenance too. I think you should either learn about air brakes, hire someone who knows about them or just quit driving vehicles with air brakes.
