I have a 2009 Softail FLSTC. The dealer did the 1,000 and 5,000 mile service. At 5,800 I had an independent with years of HD experience and a very good reputation change the rear tire. I was riding thru the Pa. mountains on Sunday and lost the rear brake. The pedal went to the floor and I tried to pump up the pedal but no luck. I was thinking of going another 20 miles to town using the front brake only. Lucky for me I decided to pull over on a safe spot in the mountains to check it out. The rear brakes then locked up and I could not move the bike. Had it towed to the Harley Dealer. Harley Dealer noticed the new rear tire and says when they changed the rear tire the brake pad on the bottom was not inserted in the spring clip and slid down. It is held by a pin on top. When I hit the brake the first time the caliper piston was not in contact with the brake pad and popped out causing the pedal to go down to the floor. The pad then wedged into the rotor and locked up? I rode for two months and over 800 miles since the tire was changed and had no noise or problem with the rear brakes? The bike now needs new pads, rotor and a caliper. Dealer wanted around $450 to fix it. Already paid $250 for the tow. Is this a HD problem or do you think the tire change caused it? The independent has the bike and is fixing it on his own dime. Just a heads up if you are changing your own tire to check the brake pads.
