I actually decided to take the pads off. I did it the difficult way by taking the pads off and then the "ring" off. Then I thought the ring needed to be put on the pads without realizing the new pair came with them already. I thought I broke it at that point since I couldn't figure out how to put the ring on the plastic part of the pads then I looked inside and saw the exact same part inside already. After you take it off you can just push it back in although it does take some effort since as one part clicks the other side seems to unclick so took a bit of effort but overall not too difficult. If you look at the pads as a D there are two "weak" points where they click. Those are where the top and bottom of the D form where it goes from straight to the curve of the D. The different is pretty major as my old pads should have been replaced a long time ago as they were flaking off.
