Service Brakes, Hydraulic:foundation Components:master Cylinder 2014-11-24 · campaign 14V750000 · 1,560 vehicles

Defect: Harley-Davidson Motor Company (Harley-Davidson) is recalling certain model year 2015 Tri-Glide FLHTCUTG motorcycles manufactured July 14, 2014, to October 15, 2014. The affected motorcycles have a rear brake master cylinder assembled with an incorrect piston. This piston may not provide the proper support and may allow a tear in the primary cup.

Risk: If the primary cup develops a tear it will decrease the brake performance, increasing the risk of a vehicle crash.

Fix: Harley-Davidson will notify owners, and dealers will replace the rear master cylinder, free of charge. The recall began December 16, 2014. Owners may contact Harley-Davidson customer service at 414-343-4056. Harley-Davidson's number for this recall is 0162.

Service bulletins (43)

Technical service bulletins are repair instructions manufacturers send dealers for known issues. Unlike recalls, the fix is not automatically free — but naming the bulletin at the service desk can save diagnosis time and support goodwill repairs.
