I had a very low mileage 1 ton 1961 grain truck. It had a booster on it and the stopping power was amazing. My 61 K-10's brakes are all new, bled, well broken in, and they suck in contrast. It is about the heaviest version of a 1/2 ton pickup available, so a booster will be added. LMC carries 3 versions for our trucks for pretty reasonable money.
