Re:
Sold the big 203mm front disc and matched the rear with a 180mm.
The front brake hasn't felt right since I fitted it though, much stiffer lever feel than the rear, and very sluggish response.
I cut the hose to shorten it when I fitted it and used a new olive and barb, but kept thinking maybe I'd done something wrong....
I sat and bled the brake properly, let it gravity bleed.... any way you could think of I tried, but just could not get it to feel right.
Obviously I've been out on it, and the brakes stopped me ok, i just gave the lever a first quick pull to set the pads then hauled on it to pull me up! Not ideal, but it worked!
Anyway, after googling XTR Trail brake issues, I found a wee thread where someone mentioned they'd discovered the olive wasn't sitting correctly in the lever housing, that he'd undone it, wiggled it around, re-tightened it and fixed it!
So, I've just done the same, and as if by magic, I now have a fully functioning front brake! And what a difference, all the modulation you could wish for combined with fork-bending power!
The power of the internet comes to the rescue!
