Off Grid Bicycle Disk Brake Pad DIY Adventure - Hybrid Solar Powered Electrically Assisted Bicycle!

Several months ago I bought a new E-bike, but the brakes were always squeaking, not stopping satisfactorily, and wearing out way to quickly. Join with me as I figure out that these brakes had needed, and will need, frequent adjustments. There's not any information that I can find explaining the quirky back puck configuration, so I came up with my own set of standards that are working so far, almost a month later.
The one thing I didn't mention: I believe that the brake rotor, or "disk", is designed to flex inwards towards the pad on the puck as the pad from the levered side pushes against the outside of the rotor. That is why there are "spokes" instead of a solid plate by design. That is my theory so far as to how everything keeps from making contact, then evenly distributes the resistance while applied, when adjusted and maintained properly.

I think I didn't do something correctly in this video. The pad on the rear puck should be put all the way in against the disk rotor, tightened up from sideways adjustments, then backed out incrementally until it doesn't rub. That way it minimizes flex on the rotor, minimizing the need for tightening to one or two times before replacement, and maximizes the wear time by putting more load on the puck's pad more evenly balancing with the levered pad.
I'll update after adjusting my brakes in the next couple days. I'll let you know how they did with the estimation method in this video versus what happens if I install the caliper and tighten the properly adjusted sideways adjustment before simply setting the puck all the way out against the disk rotor and finally backing off the puck instead of starting off somewhere in the middle.
With these narrower pads, I think I may be able to set them all the way out so they don't need tightening until they are completely worn. I need to make sure I keep up on their wear to avoid unexpected trouble in the middle of travel. I should've explained how to do routine sideways adjustments too, but I've not yet articulated how to do it yet. It is due very soon, so I'll make a video showing that off. Basically make sure the puck has enough material sticking out and double check the levered pad too. Tighten the cable adjustments then retighten the cable with the bolted clamp and loosen the sideways adjustment bolts. Hold the hand lever tight while tightening the sideways adjustment, then back the puck out until it doesn't rub at all. Don't forget to tighten the puck's retainer key and double check the cable's tension and you're good to stop after you go!
