Yea, they look OK from here singh. Check the book for minimums, if they list any.Some of the old pads had a red line around them as an indicator, I don't think these have any. I think Ducatiscotty found a good after market equivalent, check with him or scooterbob. I seem to remember them talking about it. It Looks like you still have a few miles to go though.
1. Another good thing to do whenever you have the pads out is 'deglaze' them. Just put a little 220 grit sandpaper on a flat piece of glass and sand the pad. This breaks the glaze that often occurs over many miles and gives the pads more bite. 2. Also, you can sand a little angle into the leading and trailing edge of the pads. This helps limit squeal too since you don't have a sharp edge meeting the rotor. 3. Finish off by scrubbing the rotor with a green 3M ScotchBrite pad and brake cleaner.
IMHO, I change them out before they get to the slit. I believe the slit is to allow water to escape when you brake in the rain.....
No Sir the slit allong the pad is there to let you know your on the absolute max of wear and nothing to do with water so what you are doing by changing slightly early is good sense .Don
