I just redid all of my brakes and kept everything stock. I have been driving around the past 5 weekends (max 45 mph) and I have not had a single problem with brakes, except for a little squeaking.
In the future I plan on doing some work to get highway speeds, and at that time I will probably put disk brakes on for safety.
For right now I just wanted something I can cruise around in. I just make sure to give myself some extra room when I am stoping. I would hate to see what a 1 ton would do to the rear end of a Prius.
