How are the newer shimano brakes? Ive got a set of the M675 but im looking at getting a new 11 speed groupset, brakes seem to come at a decent price as part of the whole groupset but are they any better/more reliable than the 675s?

doubt they will be any better

I seem to get the wandering bite point thing but seems to be fixed by taking the pads out and squeezing the lever a few times occasionally. Other than that they’ve been pretty good really.

Night and day difference. Shimano hat some problems with the new XT’s and XTR brakes but that has since been solved.

The newer brakes feel much much better than the older ones, mudulations and feel have also finally been improved.
