I could be wrong, but I thought that the straight bead offers more surface area for the tire and sealant to maintain an airtight seal, even under more sidewall deformation found at lower pressures....

Pretty much. Add on the much higher leverage and surface area of a 622mm "disc" and you have a very heat resistant system, overall.

I wasn't suggesting rubber pads prevent rim wear. I was only suggesting that pad ablation is the trade-off that prevents the pad/rim contact from getting hot enough to lose friction.

Brake fade can happen with mechanical discs. Get the pads and rotors hot enough and they stop acting like they have friction on each other. That doesn't happen with rubber rim brake pads because the...

My original point was that maybe, like many cyclists do, the OP was relying overly on his rear brake due to the "I'm afraid I'll flip over the bars" phobia. Distributing and alternating between front...

Front braking is more efficient, so it should control speed with less friction heat.
