Got a 2010 triglide, a strange thing happens when I apply my rear brakes kinda hard, not a full lockup brake apply but firm. This happens when I downshift to first with the clutch in. I rarely use 6th gear, except on the highway. This occurs when riding around city streets. The light doesn't stay on just flashes. Not sure how long it's been doing it, I noticed it when riding at night. I did replace my brake pads in the rear about 500 ago. Not sure why the brake system would be linked at all to the trans. Anyone run into this?
