Hello. I'm currently in the finishing processes of building my Cb125. I had to order a (used but new to me) and I can not get the pads to come apart. They were apart when it got here but I had to force compress them due to the internals being seized. Any tips on how to break it apart so I can finished rebuilding the caliper. I do have a spare parts caliper and it is just the pad that is stuck. Thanks!
