Can someone give me advice regarding the best foot position to adopt for using the rear brake. As a newbie I have spent my first few weeks with the heel of my foot on the peg and the ball of my foot "covering" the rear brake lever. Unfortunately I can't do this without depressing the brake slightly which in turns activates the rear brake light. I don't think this light touch is actually engaging the rear brake. So now I have changed my foot position to one where the ball of my foot rests on the peg most of the time and I move it to the brake leaver when I need to brake. I wonder how safe this is? What do other people do?
