I was putting my master calendars in my pedal box today and noticed that one of the master cylinders clicks as the plunger is pushed and released. I don't have any fluid in it, so maybe that is the cause but I wanted to check to see if I should be concerned. I don't know how to bench blead it to check it and I don't have any of the hydraulic lines hooked up yet as I am waiting for another reservoir which they are out of stock of right now. Am I just worried over nothing.
