Guys, tell me if I'm wrong, as if I doubt you will, but there is a massive difference between " testing" the rear brake and using it in conjunction with the front to execute an emergency (or panic if you like) stop.
In an emergency stop the front brake application produces weight transfer to the front. This weight transfer is accentuated by, in most cases, if not all, by the riders weight being transferred from the pegs to the bars. This will produce a front rear weight ratio of up to 90/10 (source Keith Code). Therefore rear brake application will initiate a lock up in an emergency stop well before a rear brake only application in a "test the rear brake only" scenario. So if you doubt that the rear brake is effective and will not lock up try a balls and all emergency stop. Just watch that the bike doesn't swap ends. Also if the rear starts to slide and rear brake pressure is released with the bike not tracking straight then, when the rear wheel regains traction, look forward to the high side which is about to occur. If the rear wheel locks you are, in most cases, best to keep it locked and steer out of the slide.
Cheers
