    So after ordering new brake lines, I went to order new fluid, question its what's the difference between 4 or 5 or race fluid? Or are they all the same on road use? Can't seem to find an answer on the search, thanks

    If you are going to use 5 you will need to clean out the pot and master as it won’t mix with 4.
    5.1 is an upgrade on 4 and will mix with it as same material so to speak with a higher boiling point and race doesn’t fade at all but you can argue do you really need it on the road?

    Great stuff, looks like 5.1 could be the best bet then. AP race isn't much more expensive to be honest but like said above is a bit overkill for road use. I'll go 5.1 and just make sure everything's clean and dry before replacing, cheers lads
