You can never be to safe with the brakes on these old trucks. With a single master cylinder if you lose 1 wheel of brakes you lose all breaks. I had 1 leaky wheel cylinder and the other 3 were old so I swapped out all 4 for safety. That will be the best $200 you can spend if you plan on keeping the stock brakes. While you are at it take a good look at the lines too. I put in the wheel cylinders, a new master cylinder, and new shoes. I made it 15 feet and blew a brake line. It rusted out.
