In an emergency situation, especially one caused by or running across rough/uneven surfaces, the rear brake is a priceless tool.
I use rear brake often, almost always, in varying combinations with the front brakes, for stopping power, for suspension control, for control of all kinds of bike action and reaction.
I understand WHY MSF and basic motorcycle training recommends against overuse of the rear brake. However, on this forum and others, it's my opinion that I see way too much preaching against the rear brake and not enough education on how it can be a very effective tool to help manage the bike in adverse conditions.
* Gravel
* Snow/ice/spills
* Rough pavement surfaces, both straight line and sweeping turns
* Slow turning
* Sudden load shifts, as in striking an object underneath and the passenger suddenly moves forward
Beyond what's listed above and at an entirely different level, there are "performance handling" reasons to use rear brake, which admittedly, are probably not appropriate for most street riding and therefore should not be taught in general street classes.
I guess I'll continue to be the one pushing the pendulum in "the other direction" to point out that the bike HAS a rear brake and it CAN (and IMHO should) be used in a very constructive and safety-enhancing manner. Like everything else, it takes practice to get it right and make it a reaction, rather than an afterthought.
Personally, I've had three situations in two years that would have, without any doubt, resulted in me going down and possibly being killed, if I had not reacted with proper use of rear brake, AND REAR BRAKE ALONE.
I feel better now!
Now, more to the point of the beginning post of this thread...
I've logged over 50,000 miles on the 07 thus far. I replaced front pads at 36,017 miles and replaced rear pads at the same time. My notes indicated the rear pads were trailing about 10,000 miles behind the front pads, and would have likely made it to 50,000. That should speak empirically of my rear brake use.
