I'm having tons of trouble setting up my new 03 XTR brakes. No matter what I do it seems to be leaking fluid slowly from where the hose connects to the lever housing. I replaced the o-rings, still leaking. I put teflon tape on the bolts, still leaking. Did I miss something or is there some additional advice someone can give. If not, I'm gonna take it to the shop and shell out some labor fees. Please help!
