190,
I did try reversing the channel and got the same response. I even tried playing with the travel end points since that varies the pulse width of the signal. And I even tried narrowing and moving the end points so that neither the gear or brake was operating in the same pulse width like single servo lead controlling but no different result.
I wonder if there is a magic initiation sequence to get a factory reset?
I did some of the LEN TODD brake tuning and getting better brake control. Could be better but no data port on my controller. I may play with putting a variresistor in line with the brakes I definitely have a stronger signal on one side and moves to the other when I swap leads.
The surface of the disk appears to be galvanized, mostly zinc, which is soft. It may be an issue if you polish through it and base steel would rust. Upgrade to stainless and carbon steel disk sandwich???
Oh well, a new hobby to have ele brakes. I think I am going to build a true ABS system. Before I need the air tank for me
