Can anyone explain to me "technically" with as many details as possible why everyone swears up and down to NEVER use the rear brake ?? In my ever evolving quest to become a better rider, I have been teaching myself countersteering techniques, reading every article I can. I had a buddy of mine that is a rocket scientist (literally) try to explain it to me today, but it ended up sounding like "You just do it because".When I am going slow (under 40) and come to a stop, I lightly apply the rear brake and then the front as needed. On a fast turn or sudden stop it is pretty much the same, just harder pressure on each. If the rear brake is so worthless and it only provides 30% of your braking power (which I understand), why is there one at all? My buddy was saying "the rear applied at the wrong time can actually cause more problems that it helps.
