The topic title pretty much says it all... I have two sets of XT M8000 brakes and, naturally, I'm a little confused (and concerned/irritated) by all the comments regarding modulation and other issues. And equally so by all the praise showered on the M7000 set, since I spent more on mine. I haven't had any issues since fitting either set around 6 months ago. And whenever I speak to guys at Revolution cycles and This Way Out, everyone prefers the M8000 over the M7000 and doesn't know of any issues either. On the Hub, however, there are a lot of people who talk about the M8000 set as if it were a bad flu going around that they're pretty chuffed to have dodged. So what gives? Surely any real issues would have been corrected relatively quickly?
