I was surprised at how clean the brake calipers and wheel archers were, after driving more than 10K miles on my RWD Premium 68 kWh MME !!! There was no grease or road grime attached to the calipers and the absence of brake dust was truly amazing .... compared to my Mercedes GLA, the silvery wheels would have turned grayish black at this mileage level; in addition the thickness of the disc pads was like it came out of factory.

Yes ... this further reinforces how the concept of One-Pedal is superior to the traditional braking system of the ICE vehicles.
Even if you donā€™t use one-pedal mode, mach-e uses regen to slow the car almost all the time.
Someone on this site did a test where they put a shraprie mark on the brake rotor to see how long it stayed in the different drive modes. He was surprised to discover that it stayed there even in normal 2PD mode also.

Which is the problem after washing the car. Trying to heat the rotor to help dry it requires going out of your way to stop agressively and score a 50% or lower on the brake coach!

I have to drive the car after I wash her every time.

Here is the link: https://www.macheforum.com/site/threads/mach-e-brake-pressure-data-for-each-drive-mode.11284/

There is a lot in there, but the punchline is that the car strongly prefers regen braking in all driving modes (whisper/engage/unbridled, and 1pd/normal). How it feels changes a bit depending on the mode, but if you tell the vehicle to slow down, it will prefer regen up to around 0.2gs of deceleration (on an AWD at least).

On a normal drive, it is quite possible that the only time the friction brakes engage at all is after you are already stopped (it uses them to hold the car in place when fully stopped). Even at less than 10 mph it will use the regen to bring you to a stop, then hold it with the brakes. I have several datalogs of 1+ hour long drives (through towns, not interstate) where the friction brakes weren't used to slow the vehicle a single time on the entire drive.

Most of the dust youā€™ll get is from clearing the rust from the discs lol.
Im contemplating doing 5k miles rotations Instead. Between regen and acceleration the rear tires on a RWD will wear a lot faster than the front.

Regen vs friction braking is the same as far as tire wear. Is concerned The tires canā€™t tell whatā€™s slowing them down. ?

Itā€™s not when only the rears are braking ?

I'd like to see some recordings of regen and braking in a RWD. In my AWD the regen is strongly biased to the front motor (even though driving is biased to the rear motor). I'm curious how the RWD handles it.

If someone curious loads up CarScanner, the points to look at on a recording would be Hybrid/EV Battery Power, Vehicle Speed, Vehicle Acceleration and Brake Pressure, with a log showing some normal driving, some 1PD "let off the pedal" slowdowns, and some "rapid slowdowns" using the brake pedal.

Same here, even on FWD vehicles I have owned, the rears have always cupped badly. Always crossed the backs to the front because of this. The manual recommends crossing the fronts, regardless of which wheels are driven. Is that best for RWD?

Crossing the fronts to the back is common for RWD and AWD vehicles. You usually cross the non-drive wheels which is why FWD crosses the rears.
it you have directional tires, you donā€™t cross at all.
