Carbon brakes offer the same stopping performance as steel brakes but with the added benefit of a significant weight savings, which ultimately increases fuel efficiency. Next-Generation 737s are already lighter than competing Airbus models. This structural efficiency is a fundamental reason why Next-Generation 737s fly farther, higher and with better fuel efficiency than the competition.  -   Mike Delaney     Quotes
