Looking over the last coulple months (and longer) there has been some good information obout optimizing the brake system in the setting of big tires, 1ton swaps, towing, and 4 wheeling. My current situation is a 73' K5 481 bb, TH 400, 205, D60 in front with detroit, 4.56 gears and reman1ufactured Bendix caliipers and napa pads. The back is FF14 bolt with a detroit and drums that have seen their last turn so Im motivated to move forward with the disc conversion to hopefulluy get the brakes better. My plan: Use Blackwidowmounting plates/spacer. Junk yard for 76-78 eldorado calipers with e brake. I would keep the stock blazer proportioning valve in to see how it does. Does anyone know new of a truck (chev 1ton or 3/4 ton) I can use to harvest the power booster and master cylinder out of. All that is assuming the newer designs worked better and more efficiently I'm curious as to whether anyone is aware of a certain year or groups of years where the brakes worked noticably better. Thanks alot if anyone cand dig up some info on that.
