Thanks for passing on the brake rotor bobbins tip.
At 350 km +/-, I was intrigued by the rear disc dragging sound. This morning I decided to look at it more closely.
Runout on the rear disc goes from anywhere from .0000 in. to .0050 at one location. Most of it is between .0000 to .0003, with one location at .0050. This is within the acceptable standard, but close to the .0059 in. limit.
Many times, when I check a fastener on my Versys, it is either over torqued with permanent type lock-tite, or it is bone dry (i.e.: rear axle, etc.). I therefore had to check the rear caliper assembly.
It was immediately clear that the caliper holder bolt, and the rear caliper holder pin were bone dry.
I cleaned these up before applying Permatex Synthetic Ultra Disc Brake Caliper Lube to the above and to the dust boot & friction boot.
The pads didn’t show any evidence of wearing more on one side or the other. They are, after all, brand new.
I could very easily push back the piston into the caliper with my thumbs. I assume that it is functioning properly.
After reassembling the caliper assembly onto the wheel, I went around the block to see if the dragging disappeared. It did for about 100 feet.
Oh well, I’ll try a set of organic pads soon. It will be easier on the disc but am not 100% confident that this issue will go away. The disc is warped just enough to be within standard, but also just enough to drag and make intermittent noise.
