2020 RT Brake Issue - had the recall, pedal still won't return on its own! Any ideas?

Hi Everyone.

I bought a new to me 2020 RTL. This is my 3rd RT (2012, 2018, 2020). It has 16,000 miles on it.

Here's the deal. I know about the brake switch recall and it has been done on this Spyder.

However, when it is cold, the brakes work as expected. But after 20 minutes of riding or so after it warms up, the brakes don't release completely, the brake light stays on, and of course the cruise doesn't work. If I grab the pedal with my toe and lift, the brakes release, and the light goes off. The pedal doesn't return fully on its own. I know it's not just a mis-adjusted brake light switch because I can tell the brakes are dragging until I lift the pedal, then they're fine.

I have cleaned the brake pedal pivot and it seems free. I also cleaned around the pivot near the brake switch where the brake pedal rod connects. That also seems fine. I also replaced the brake pedal tension spring with no effect.

Does anyone know what might cause this issue only when the Spyder is hot? I would take it to the dealer but I'm afraid they won't take the time to ride it long enough for the issue to happen and just say it works fine.

Thanks for any ideas!
Layth

You say the brakes are dragging... are you sure of that, or are you just going by the light? I know you said you checked and changed the spring, but if you are lifting it with your toe and everything is good to go, it sounds like that return spring is not tight enough; or your switch needs a little tweaking as it's not coming into play where it should! On the older bikes we had to put a double set of return springs on. They are real close to the header pipe, maybe that is warming the spring up enough to weaken it a bit, hard telling not having it in front of me! Good luck, a shop will probably change the switch and send you out the door! P.S Have you done a brake fluid flush yet?
