Shimano ST-A410 / Shifters Dismantle / Break Down - Part 1

After a failing attempt to repair my left shifters, i've recorded the dismantling of the right shifters, supposed to be similar. I successfully repaired in after removing all the hard grease and thought it could help others. I only used basic tools as well as tweezers. Model is Shimano ST-A410 similar to other ST Models. Goodluck !
