Ok, I give up! DOT3 or DOT4?

I have spent an hour searching online and in my Ellery service manual. Going to bleed the brakes next week, what fluid does Toyota recommend?
 
My Haynes workshop manual asks for Dot 3. But that manual was written before Dot 4 came about. Dot 4 supercedes Dot 3. You can use Dot 4 where Dot 3 is requested but you can not use Dot 3 for Dot 4 applications.

Dot 3 and 4 are both glycol based. The later having a higher boiling point.

Dot 5 is a silicon based fluid and can't be used with either of the above.

Dot 5.1 apparently can be used in Dot 3 and 4 applications according to this article but I've never heard of it:

Do you use DOT4 for power steering fluid ? Am I the only using Dex3 for power steering?

No, sorry I got confused, That was a mistake lol. I'll go back and fix that.

We've finally got some warm weather here and I've spent 2 big days out on the water fishing in my kayak. I'm beyond exhausted! For Power Steering, I used this product -> Power Steering Fluid & Stop Leak - 1 Litre - https://www.supercheapauto.com.au/p/penrite-power-steering-fluid-stop-leak---1-litre/342317.html?cgid=SCA01070503#srsltid=AfmBOoqL8IUQoWkIPyxcNwm2_HUVQCySKtE2PyEwhcxz7FtnXyH7TJtN&vid=1%2B41KyNDUNsFDwbFOKbYKA%3D%3D&start=1

Brakes I use DOT 4 as it is recommended for Dot 3 and 4 systems. Had no problems at all!
