Hi Pete,
I don’t know if my previous response got to you so I will send another.
<<it’s loud, and not to mention that atomized brake fluid goes everywhere>>
That is why I recommend using a grease gun. The pistons quietly pop out without spray and flying missiles. Someone complained that it took a lot of grease and was hard to clean out but you don’t have to use just grease, you can first fill the cylinder with water, then put in the fitting and pump the grease in. Once one piston moves just a little, you can clamp it and then pump some more grease in until the second one moves.
