Had a first this morning, my rear brake froze on. I've had levels get stuck but this was the brake caliper sticking after pulling. I had to got off and physically push it back. I think it was a combination of rain yesterday, lots of wet leaves, and then 20 degree temp drops. Good thing we have 2 brakes!
I've had that. I think moisture gets into the cable housing and then freezes, causing the brakes to stick. I've even had it happen mid-ride where I start off fine and after a few miles I no longer have brakes.
