As a Stock Leopard racer, I am for allowing single brake systems in our class. If a racer feels they need to have a dual system, they are still allowed to use it. Otherwise, a single system will work. IMO.
This ruling should have been broken down by the classes, as it seems the 4-Cycle racers do not favor this.
Karts are generally made with a single system. It has worked for years, and I don’t see why it can not be made an option to each single racer.
