No rear brake again

I just have a hard time trying to see the Brembo Stylema pistons are sucking air. Of all the bikes running them the new gen R3 is the only one having problems.

I have the same calipers on my KTM 1290 Super Duke and have never had to bleed them.

you make a great point about just the rockets having this problem
something for me to consider.

DOT 5 brake fluid is not compatible. Maybe you meant DOT 5.1 instead?

No testing? What do you mean boiling some brake fluid under pressure at different wet levels? I don't think any of us has the laboratory to do that. I trust the testing already done. Even Triumph is now saying its just normal degassing. Did you see that? What causes degassing of brake fluid besides temperature?

We have a design problem not a air intrusion problem. The gas comes from the excessive heat where the components are located.

you seem to be dead set about boiling brake fluid with out even testing the what heat the brakes are getting up to

lol, my brakes have to be pumped up before even getting the pads warm. so it's not heat from the calipers.

My situation may be different than others and my opinion of the rear brake is definitely different than some. There is little doubt to me, and I say this about my GT only, the hot weather with hard stop and go backroad riding and abrupt slowing/ stopping causes my GT to get very hot. The rear brake goes to the floor after an hour or so of very aggressive riding. Maybe not right after a bleed but a month or two of once a week hard backroad riding That’s pretty much it. Now my current situation is a little different as the rear brake is slowing going down monthly but like I said. If I hit it hard on a 100 degree day within the hour it will gone. I have to believe Turbo as the evidence points in that direction. Once again this is ‘my Rocket’ as I can’t speak for anyone else. It’s the friggin heat!!
Edit: just for info. I take it relatively easy now and only kick my heels up maybe once a month or longer and this is due to fear of my brake going down. It really does suck. I now wish I kept my 2014 Rocket. No problems with my brakes on my 14. Cheers

Well i once needed info about atf so i put a pan of atf on an outside stove and found it was steaming and breaking down at 250 degrees so yes i try to find answers.
yes i should have typed DOT 5.1 i will try to be more careful when typing for you. sorry i typed info instead of information.
i can clearly see what we have is a failure to communicate probably my fault especially cause i think you already have made up your mine about the cause of the problem. so i will quit wasting my ime
