I'm currently rebuilding my front caliper and I would like to know how to remove the pistons. I know that MikeXS sell a tool for that but the description tells that it works for 77-84 XS only. My bike is a 72. Does someone have a tip for that ?
72xs2, DOT 3 is fine to use. you can use DOT 4 but it is not required .... just don't use anything petroleum based (oil P/S fluid Hydraulic oil etc) The petrol based products will destroy the rubber in your master cylinder, hose, and caliper and you will have to do it all over again.
