Hello guys n gals, bit of advice required please.
Need to replace the brake fluid in my R53 GP.
I honestly can’t recall what was used last time.
Question, is there any benefit to going to Dot 5.1 over Dot 4?
Any brands preferred over others, or are they pretty much the same?
Currently looking at 5.1 from Brembo on Opie Oils, as I’m about to buy 5L of Motul BMW LL-04 oil for the annual oil change.
Any advice comments etc much appreciated. Ta.
