Mine did the same thing . I looked in the book it says to pump it a time or two then set it . Seems to work better now.

 

ask my buddy about his parkin brake on his 500 scrambler.he pushed it out of his garage,which has a steep hill next to it.he locked it down,went back in the garage,heard a crash,his bike rolled down the hill crashed into a tree then rolled.it suc@s crashing your bike,but really sucks when it crashes and noones on it.
