Ford stops taking orders on the lightening

So I'm not too familiar with the regenerative braking system. Can you explain a little about it? I'm assuming it isn't traditional rotors and pads that create heat, but resistance motors that recharge a battery.

Does that create any heat?

Does regenerative braking eventually wear out going down a long steep hill?

Does it provide sufficient braking for a heavier trailer? I'm imagining my Ram with exhaust braking that literally requires no manual effort on my part and keeps my speed down with ease.
