I had that added to my 4runner for $500 or so total (cheap kit from AirLift).
All wakeboard boats should have brakes on at least one axle... however, Washington state requires boats have brakes on BOTH axles. Oregon does not, I don't believe Idaho requires it either... so if the boat was originally sold out of state, it's something to look in to. Adding brakes to the second axle can be done for about $600 or so.
