They don't. If you have decent rim brakes, good rims, and a dry road, it makes no difference. I've been as heavy as 266 pounds and was never unable to stop on a steep descent. Now I'm around 210 and I have purchased an Open so I can run bigger tubeless tires. It has disc brakes, but not necessarily for better stopping.
