I need to change the brake fluid in my car, but I'm not sure if I should useDOT 4 LV or DOT 5.1. Any advice? Does anyone have experience with this or know which one would be best? I am grateful.

Is this something you've done before? If so, which brand would you suggest?

Sure, but not on an F33; instead, I use a pressure bleeding kit; Castrol costs about £15 per litre, and BMW is another option.

Yes, I understand.
