U.S. Citizen would like to bring brother (over 21 years old) to live in U.S. permanently. What is the fastest way?

If your brother is single and remains single, your petitioning for your parents and them petitioning for him would take approximately 8 years.  Your petitioning for your brother alone would take approximately 12 years. There is no faster way for you to petition for your brother first and then petition for your parents as there is no connection in that case. A faster way would likely be trying to match his education and skills with a US employer that would be willing to sponsor him for a working visa/green card, or if the working visa is not possible, directly for the green card. Such a process would normally take 2-3 years assuming that your brother is not born in either India or China.
