I have experience of the front brake binding. Background: I'd had a new tyre mounted, and as I always do I went for a brief ride to check it had been correctly balanced, found a clear road, took the speed up to "quite high".
After a while, it seemed that the engine started lacking power, bike wouldn't maintain its speed. Even at full throttle, it started slowing. Changing down still didn't prevent it slowing. My first thought was something wrong with the engine. To cut a long story short, for whatever reason the brake's hydraulic pressure had maintained, the discs warped obviously pushing out on the pads, making the pressure even higher.
I don't know whether the discs were glowing.
After I'd stopped for several minutes, the binding lessened, I was able to move again. The front brake was now useless (lever could pull to the handlebar without any significant retardation), luckily I was only a couple of miles from home, rode back very carefully with only a back brake. Oh, and the front discs were "psst" hot when I did a "dab the disc with saliva on finger" test.
Whatever the cause, it was fixed under warranty [bike was seven months old] by my dealer. The new rotors, complete callipers, pads etc and the work all paid for by Yamaha. (Pickup from my home to the dealer wasn't covered by Yamaha, but my dealer didn't charge me - "We don't consider it fair for the customer to be charged for collection when it's a warranty repair".
Point is, even though there wasn't enough engine power to keep going, at least on a dry road, the wheel didn't seize, the tyre never lost grip. I suspect the high temperature caused brake fade before it could get to a seize condition.
Warped rotors:

The brake operation after it had cooled would be compromised because with the now warped rotors, any brake pad pressure would tend to straighten the warp rather than grip the rotor, hence the peculiar brake lever behaviour.
As an aside, I'd got the new tyre on a Monday because I was catching a ferry on the following Sunday for a trip around Spain. Phoned my dealer Monday early afternoon. He was overloaded with work. Having explained my situation, he got on to another of the three dealers under this ownership. This one one collected the bike that afternoon, assessed the problem, persuaded Yamaha to foot the bill, ordered the parts special delivery, did the work, all finished for me to pick up on the Friday. That's good service.
