Thanks Jake. I flush the fluid annually and usually have to change the pads about then, too... I'd bet there might be something going on with the actuator in the tongue that's setting me up for failure and causing those calipers to stick. The seal between caliper body and piston is still intact so as you said it may be the fluid causing the issue.

And Forrest I'll have to try that stuff, too. Being that I drop the boat on a ramp in the everglades, they get really hyper about any petrochemicals in the water. Even bearing buddies cause frowns on the faces of those dudes with guns and badges (although they probably have a chip on their shoulder anyway...)

I show them I use food grade grease which doesn't work as well as Red tacky #2, but I learned that from having to deal with the same issues on farm irrigation pumps dripping grease in the water canals..
