I have flushed the whole system changed everything from gaskets to hoses just in case there was a contamination problem. And it still keeps getting stuck to the reservoir and I’ve bought several brand new cabs and they all do the same thing ---

as long as its not leaking and everything is working it should not be a problem. ---

Yeah, so do mine. Reach in there and pull it out. Nothing to worry about. ---

and if it really bothers you, find a rubber safe glue and glue them together. but there is really no reason to have to do that. ---

That’s not unusual. It means the gasket is forming a tight seal against the fluid reservoir. How often are you taking the top off the reservoir? I mean you can see the fluid level through the side. I can’t see a reason to have the cap off more than once a year. Ideally it shouldn’t ever come off unless you are doing brake service. If you’re taking the cap off regularly to fill it there might be a leak somewhere. ---

The brake MC cap on my Ford truck is vented, although the vent hole is very hard to see. I have to hold it up to a bright light, then I can see a little light coming through. As the brake shoes/pad wear the fluid level drop, so air has to come in at the top. Maybe the problem is something to do w/that.
