The HS-11 brake levers do tend to break easilly. At least more easilly than HS-33s. Look on the Magura website (
www.magura.com), click on bike components, and then brakes, and they have a full manual on how to bleed them. I think it is also in the manual given with new breaks. I'm not sure whether or not you actually read my last post, but if you're careful, you shouldn't need a full bleed.
Cheers
