Help decoding parts numbers (letters specifically)

[Soulprogression108]

Any Toyota techs have a key for understanding parts numbers better. I've seen a few things but not this specific number code. Looking up brake fluid for my runner and there's too available.

00475-1BF03-PR (What is PR)

and

00475-1BF03

I know there's a lot of codes and I can't seem to find a good reference key for it to understand when looking up parts.

00475-1BF03 is the correct number. when I search PR I get prius that comes up, I think there is also a version with -LX at the end for Lexus LX. I am not sure why, but the black bottle with the red label and gold coloured rotor is the bottle you want

Cool thank you that makes sense. Maybe the Prius uses slightly different fluid or something due to the regenerative braking system?
