Question

Answer
Anytime you work on your brakes you usually get a small amount of air in the line. Anytime after working on the brakes you need to bleed the system. You can do it the old way by pumping up the brake, holding the pressure on it and opening the bleed screw. Keep doing theis until you get clear brake fluid coming out. make sure you fill the master cylinder again.
The other way is to get a vaccumn pump, attach it to the bleed screw, open it and pull the fluid through. Then fill the master cylinder.
Good luck and happy riding
