Total HBF 4 brake fluid

[seanf]

Thoughts on this? seems like its not readily used in North America. Got some from a friend who does some parts wholesale for about $14L. He suggested it when I asked him for some Pentosin DOT4 LV. I figured the Pentosin would be good when its -25C since my pedal feels kind of hard until the engine bay warms up. I notice its viscosity is higher at -40 than the Pentosin but I'm not sure it will make a difference, I'm sure just fresh fluid will help.

I just put some Pentosin in my 85 rx7. I quite like it. I flushed with cheap dot 4 until All of the brown rusty stuff was out then followed a flush up with Pentosin Super Dot 4. I would have used the LV but I figured my 30 year old car wouldn't care as whatever name brand brake fluid would be far superior to what was in it from the factory 30 years ago.
