Has anyone had to have their 256 rear brake posts re-faced? I've been struggling with a weak and dragging rear brake since the beginning. I always thought it had to do with the fact that I had to cut the rear hose and re-bleed. After a dozen rear-bleed attempts and a month at a LBS (not my usual one, I tried to save the hour drive), it's still happening. I finally got a hold of someone at Magura and without hesitation, he said I probably need to have my rear brake tabs re-faced. The bike shop opens in a half hour, so I will call to see if they can do it, I just figured I'd ask here to see if anyone had to do the same.
