Or should I be using my brakes for slow?


What happens when you try driving the same stretch of road using the brakes to control the speed instead of the engine?

The hard of thinking will probably give you the standardised guff about "brakes to slow, gears to go", but I think what you are doing is sensible in the situation you describe. With modern brakes it is unlikely that brake fade would occur, but in similar circumstances I would probably do what you do.

For example, completing all your braking in a straight line before turning into a corner. Are you really so close to the limit of traction at legal speeds that you're likely to skid off the road otherwise?


Sigh.

I'll go a half sigh, because if one is aware of what is one doing and why, taking into account conditions, deviation from the "one way" could be quite acceptable.

Fascinating. 1st gear 4500 rpm. Someone did that in my car once and I was not at all pleased. :evil:
