There is a safety Recall on all 2015 Tri-Glides build through 10/15/14. The date of the recall is: December 11,2014.
"The rear brake master cylinder on these motorcycles built through 10/15/04 may have been assembled with an incorrect piston which does not provide proper support to the primary cup/seal. This could allow a tear to develop in the primary cup. If this condition remains undetected , it could result in a reduction in brake performance, possibly resulting in a crash".
I'm having mine repaired on Thursday.
