You should see an indent on the lower fork leg, on the inside....where you can get screwdriver in. Becareful and go slow...these chrome sliders are just tightly pushed onto the lower fork leg and bend easy. Use this indent as your starting point(make sure to spray some wd-40 on them from the inside...let them soak)...insert the screw driver and lightly tap with a hammer...once you get that side to move....work your way around really easy. Once you get them up a little you should be able to pull it off with just your hands.
Its kind of a pain....because you have to watch not bending the chrome piece or scaring the alloy fork leg.
Hope this helps
