I used DOT 5.1 BF as my car spends more time on the road than on a track and didn't fancy changing RBF every 9-12months.

DOT 5.1 is nice, and there are also some good DOT 4 fluids. There is quite a lot of difference in price and specs inside these groups. Go for one with rather high boiling point. Last time I checked, Castrol SRF was considered the best, but it is ridiculously expensive, so I would not bother buying that one. If you overheat the brakes often (track days), it is better to replace the fluid more often than using very expensive fluid.

Given it is already in 40 degree territory outside this is a point to consider irrespective of track use or not right? I was tipped to go for ATE dot4 by a fellow bimmer. Any thought?

Excuse my ignorance RBF stands for racing brake fluid?

I don't think the ambient temperature matters much for brakes, as their operating temperature gets up to hundreds of degrees. The thing about track use, is that they are used very frequently, with very little time to cool down. During normal driving, they rarely get really warm, as you have to brake many times repeatedly from high speed to make that happen.

I have good experience with ATE fluids. They used to have a fluid called Super Blue, which came in blue and amber colour. Very practical when changing the fluid, as you could see where the old and new fluid was.

... Mech suggested to flush the brakes once they break in to make sure all air is out of the system. Sounds logical... What do you think?
