Your tyres grip better when allowed to roll. Why is that stupid? I would bet that a high percentage of crashes are caused by over braking.
On all occasions ?
Object of braking is to slow down IMHO so the only correct answer is
No such thing. Different situations demand different braking techniques. The only thing that is set in stone is to not have your front brake on, without the rear……….but then again, what about endo and stoppies?
Some general rules are, never touch the front brake in a corner, always try and brake hard and fast (without skidding) trust the front brake.
Although I regularly just use the front but only when I dont want to turn.
