Not related to the brake problem, but IRT towing...did you cal HOG? You're automatically a member for the 1st two years (w/std warranty coverage) so the tow would've been covered. Maybe give HD HOG a call & see if they'll reimburse???
LOL, I was on a Sunday ride with a group two months ago and a bike broke down, here in Houston. He called HOG and they told him they could not pick it up until Tuesday!!... So much for their road service; we got a local with a pickup truck to haul it for him and only had to pay him $50. for about a 30 mile trip.
