I didn't got the time to swap out the lever until now. I manage to remove the pin from the lever using a vice but the only issue is the barrel adjuster. Is there a way to remove the lever and the hassle when it comes to to putting it back together? The only thing that is stopping me is the barrel adjuster because removing it or putting it back together is the issue. Do I have to prepare to buy a set of adjuster barrel for the new levers?
