  1. 15:00 How about using an arm from the actuator to brake handle? It seems that the rope hack added so much stretching that it causes extra lag to the system. Another way would be to use actuator to move pivot point of the brake handle instead of moving the handle itself. With adequate movement of the pivot point, the same handle pressure can result in different hydraulic pressure. For example replacing the brake handle pivot bolt with a part that has off-center middle section it could move the handle pivot point a lot with only 180 degree rotation from the actuator (you obviously cannot ever get more than 180 degree range from actuator with this setup, note that you could also get faster on/off cycle with running actuator full speed in one direction).

  2. For a very slippery test surface, try dry sand on one year old dry asphalt on downhill. If you can get ABS to work on that, it will be good.

  3. 8:20 the actuator rotates around then handle bar which obviously prevents the system working as designed.

  4. 3:30 At least car ABS systems use hall sensors and iron disk with slots to make sure getting dirt into the disk doesn't affect the behavior too much.
