you just get used to it and use common sense

 Late comment here but with riding brakeless you need to kind of think about speeds etc, like say for example you're going to do some stair drops you need to be on point with judging speed or you're either going to land to flat(well, over jump and kill your wrists) or come up short and destroy your back wheel on a stair. Brakeless is so fun. Best thing ever in my opinion, helps you learn more!
