I would simply go to your shop (if you bought it there) and have them get a replacement from SRAM...
There are two reasons you don't hear much about this big problem..
First, it's not a huge problem... (that is NOT to say that there is "no" problem...)
Second, SRAM take care of this stuff exceptionally quick.
your shop should just give you a new lever (Off something in stock) and take care of the wait on their end with SRAM...
Sorry, couldn't resist
I know a good shop would give you a new lever and wait for a replacement themselves, but the reality is that not every shop is like this. Mine didn't want to give me a new lever, and I don't think I can make them (they're not obliged to to so, right?).
And here in Europe Sram isn't exceptionally quik, as I've had to wait over 6 weeks for a replacement lever each time (and the last time I even made sure the delay wasn't caused by the shop).
So I had to dismount the broken lever, mount a spare lever and rd (shimano) from my training bike, put different cables and new bartape on and then do the same routine after receiving the new lever.. only to have to do it all over again 6 months later when it snaps again!
In proper perspective there's offcourse more important things to care about, but imo this is fairly annoying and Sram just needs to work this out..
