I don't understand how American ingenuity and know how can build a space craft that can stand the rigors of launch, travel millions of miles to Mars through empty space land on a distant planet, be exposed to extreme temperature changes and 200 mph dust storms and work flawlessly for years yet cannot build trailer brakes that will last 3 years without going to hell in a handbag. Yes I rinse after every dunking and do regular maintance. Just venting while I wait for the penetrating oil to work.
