Use of brakes are often not the right way to avoid accidents. Riding a CB750 needs a drive that never trust the others on the roads or beside them. A bike rider need to have clairvoyant abilities. It will come with experience. Watch out for women and telephone maniacs.
I have mostly geared down and twisted the throttle and avoided cars suddenly doing bad manouvers. The road is wide, bike is narrow just keep the cool head and twist it. This was decades ago, before people driving and usng telephone.
Know before it happen that the cars will not see you or just ignore you and cross the road. Driving fast on country roads, be prepared to meet a slow going very wide tractor with shapr toool behind when the farmer is travelling from barn to the different fields. This is typical for some parts of the year. Prepare fields and harvest time.
Different animals that will jump infront of the bike. A very loud 4-1 has helped me to avoid animals. Some small animals, just smash them, no idea to hit the trees beside the road in a bad attempt to avoid a rabbit, cat or other small meat.
