I ride my bike all year round, and through this winter it has got pretty grubby and my pads were starting to bind a little. So took the callipers off, pumped the pistons out a bit to clean them (not too far), and then pushed them back all the way in. They were actually moving pretty freely. Cleaned up the pad backplates and the calliper body, as the corrosion was causing the pads to bind in this area. Put it all back together. Did this on both front and rear pads. However, I cannot get the pads to pump out against the discs, seemingly having just endless travel on either front or rear levers. I've started the bike, and moved it far enough so the ABS light and Brake failure message is no longer illuminated, but still nothing. I'm guessing I have a problem with the ABS pump, but before I go too far in this direction does anyone else have any ideas. I do not have a GS911, so can't run diagnostics via this.
Thanks
