Hello from DC

Hi to all.  Bike is a 2004 K12GT owned since new.  I tried the GS911 today and  when I ran the ABS check it gave me codes17438 and 17182 which indicate pressure in the front and rear wheel are excessive.  Great, what do you do about it?  It also indicated air in the system.  The front and rear servos
are now intermittent and will work in a "grabby " fashion.  Just before the wheel locks up, ABS kicks in and releases the brake by it's normal action.

Any advice?

Cheers to all....
