Expected brake pad life, and how to tell when it's time to replace?
My 2007 650 ABS is at about 16k miles now, a lot of which is long-distance mileage with not a lot of braking. A Harley mechanic (who was jury rigging my fried starter relay so I could get home from Utah) told me my rear brake pads were just about done for. I ordered some up as soon as I got home and went to install them today. When I pulled out the old ones, they appeared to have plenty of material left. The owner's manual shows a little divot in the backside of the pad as the wear indicator. Mine don't have that, but from the image in the manual it looks like you're down to maybe 1/16" of material at that point, and I have more than twice that - maybe 3 times.
So - is there a more quantifiable way of determining whether pads need replacing? Like measuring the thickness?
And, about how long should pads last, given that most of my riding is longer distances without a lot of aggressive braking?
