I did not add a brake booster. The truck came with a vacuum boost that my father removed because it was too sensitive (but probably necessary to the first owner who carried a camper and found the 305E underpowered for the weight). I would be cautious about adding a booster if you don't need it for a load. My rear tires lock up on a moderate stop, even with the larger radial tires, and this could be dangerous with added brake power and sensitivity. On the other hand, I can still push hard on the brake pedal.
