Also, the "stopping force" has remained about the same, although now, thanks to the much improved modulation, I feel safer using the brake.
FBinNY it would seem that 2 mL of lube are enough for the rollerbrake. BTW, it's one of the lower-end Shimano models, for what it's worth. I suspect that the higher-end ones take about the same amount of lube, judging purely by the size of the case.
I suspect that even 1ml would have been enough if you rode a while and gave it some time to spread out. In any case, even at 2ml per application, it appears you now have more than enough for about 200 reapplications.
