After pulling the bike from winter storage and mounting new tires, I noticed the rear brake dragging. I can't find specific answers from searching the forum. If they exist, I apologize in advance. My question is twofold:
1. Is there a surefire test to diagnose a failing secondary master cylinder (SMC)?
2. Can the new version of the SMC issued in '09 fit my 2004 ST1300A?
Here is some background info if it is helpful for diagnosis. I have cleaned the pistons externally with the wheel off to remove any road debris. I coated the shiny pistons with brake fluid before pressing them back into the caliper. I was able to press the center piston back into the caliper with hand pressure. I am not able to push the remaining two pistons (operated by the SMC) without c-clamps. The front and rear pads were replaced in September, 2014 at 23,000 miles when the fluid was also replaced. Current mileage is 34,000.
