Right - no vacuum assist unit.Interesting, I hadn't heard about that. Looks like there's no pancake booster thingy, seems fairly compact.
The one used by Tesla (and many other companies, for EV, hybrid, and ICE applications) is the Bosch iBooster. I don't know what Toyota uses.I was considering the mechanical booster that's on teslas and a few others (it's a bosch unit I think).
Yes, it has a control unit, but if it's the Bosch you don't need to do anything sophisticated to trick it, at least for basic functionality. If you want the friction brakes to back off in coordination with regenerative braking, you'll need more - Bosch sells an additional electronic module to do that, but although this functionality is normal for even the cheapest EV or hybrid, conversions in general don't have it.I don't know enough about it yet to know if I want it. Looks like there's a control module on it which presumably has to be spoofed.
Seen anyone repurpose these yet?
Yes, lots of the Bosch units have been adapted to different vehicles, typically for EV conversions. Here's SuperfastMatt's take:
