There are two bolts holding it on. They are 6mm allen key bolts I believe. Then dismantle to clean and widen the pistons to except the new pads. Check in the articles section for a "how to"Thanks for the info but the 1100 has a different brake. I have changed brake pads in the past but these have different brackets on the left and right side. I'm just not sure how to take the left side caliper off. I just got this bike and have not had an ST before.
