It's amazing that we have any of these old trucks left to work on. If single line brakes failed as often as the gloom and doom purveyors say, they would have all been wrecked before they were 10 years old.
Same could be said of certain wheels... joking.
I agree for a different reason. I've found that it works best for me to get everything working as it was originally intended prior to trying to modify or improve it. Getting the brake system working like it should will make it easier to identify faults vs deficiencies. Faults you fix. Deficiencies you modify. Always have a clear understanding what your are dealing with.
