That single piece throttle & dual brake lever is junk.
It came on the GT1 bike and I ended up replacing it.
I now use the kits throttle, and the self adjusting dual-pull 'teeter-totter' brake lever from Sick Bike Parts LLC - Performance parts for your motorized bicycle
for $10 if memory serves.
You can see how the 'teeter-totter' arm moves to adjust for the slack in the cables and different throw lengths to apply equal power to each brake.
For example the bike in that pic has a front V brake and a side pull rear brake yet they work great with that lever.
