Great video and thank you for showing you don't need to buy a specialized tool to push the brake calipers back in place. I used a small clamp (those that are used in construction to keep two wooden boards that you glued together tightly pressed against one another...) A small clamp will suffice. On a second note, instead of using a nail I used a bolt - didn't want the pointy thing of the nail punching into the pointy thing on the pin. Pushing both ends of the break pads up also alleviates the pressure of the spring on the inside of the unit, allowing for an easier removal of the pin. It helps to have 3 hands.😁
