So I got this great distilled water bleed. It was great. As great as great gets when it's better than Magura fluid. That's pretty good. At any rate.. I've got some slow retracting pistions that showed up just this very evening after about 2 weeks since the bleed. My first guess is the piston seal in the lever is drying out from the water and slowing down the return spring action stuff? I'll try dropping some Maggie fluid in there tomorrow. Just figured I'd get some info from those with experience with water bleeds. Any extra tips on keeping the water bleed running well would be appreciated. Thanks!
