My 2006 harley davidson ultra classic front brake line failed. The motorcycle has 8,2xx miles. I squeezed the front brake lever as I was starting the bike and felt the lever fully depress. I saw brake fluid squirt on the bike and onto my leg. My mechanic says he has heard of this problem from other mechanics. I AM the original owner.

I have just experienced this personally and I can attest that hundreds of others involving several other year models have been reported in online harley davidson websites.

This fairing mount failure is present on any harley…
