Prius 3 MY 2012 brake analysis

Here is brake from a MY 2012 Prius 3, Regen Coop in yellow:

There are some differences from Yaris:

  • base value of WCyl is 0.47058824 instead of 0.49019608
  • WCyl seems to always increase when braking: on Yaris it doesn't seem to increase when only regenerative braking is in use.
  • the value of WCyl when regeneration is active is 0.49019608, just the same as the base value of Yaris...
  • regenerative braking turns of under 18km/h (I suspect the cut-off value is 12 as in other HSD cars).
