I'm not sure how to explain this. My wife took a nasty spill and dumped the right handlebar in some dirt/mud. 2009 CRF230F. When pulling on the front brake the boot/plunger that is pressed in seems very slow to respond back to the previous position. The brake lever is slow to return to the starting position. I'm not sure where to start. Do I need to bleed the brake lines. Is there an issue with master cylinder? Any help would be appreciated..
