Brake upgrade?

electronic brake booster for 5th gen 4r. not 100% sure if the master cylinder is unique because of this and maybe why we don’t see these kinds of retro fits.

 

Are you able to summarize his reasons? I didn't want to watch 11 minutes of how to change brakes. Or did he say it's because it's a well built heavy truck? It's a fairly light duty vehicle and not a heavy truck whatsoever. Every time i road trip / overland, i come back telling my wife the brakes are the next thing to get upgraded because their light duty. But, probably just different pads would work just fine.
