Default Floating rotors...

Hello Victory peoples. I'm having a brake issue with my '14 XC. Rear brake works perfect. But front brakes pulse at slow speed and have a hard vibration when stopping at high speed. No vibration at all when not braking. I've read about the floating rotors Vic has on the front with the buttons/rivets that need to be able to move. I've tried cleaning them with a drill bit and brake cleaner. It helped, but not much. Then it clicked when stopping. My question is if anyone knows a really good way to clean those buttons. Or if they're going to need replacement, can I use solid/non-floating rotors. I live in Florida near Key West. Oxidation build up is going to keep happening. Thanks in advance for any help.

It sounds like at least one of them is warped. I would stick with floating rotors.

The vibration you are feeling can happen to floating and fixed rotors. It is caused by excessive heat from hard braking. Since nobody machines rotors anymore, your fix is to replace the rotors. I would go with drilled or slotted rotors to help with keeping them cool under hard braking so it doesn't happen again.
I'm not exactly sure what the purpose of floating rotors is, but keeping the rivets clean is important. Not so much the inside diameter that you cleaned with a drill bit, but the outside diameter that is in contact with the actual rotor. Try soaking them in a wheel/brake cleaner for a few minutes (don't let it dry), scrub them down and rinse clean.

could be bad brake pads. Even if they look good they still could be bad.
lay a peace of coarse sandpaper on a flat surface and rub pads across the paper a few times making sure there flat.
youtube has some good videos about cleaning the buttons

I don't know why Victory brake rotors are so expensive. I recently bought a full set of rotors and pads for my Mustang for under $200. One front rotor from EBC is $214.

It won't match OEM though so OEM would be better if a new rotor is needed. I had this happen on a previous 04 Kingpin I had. A good used rotor fixed it. Ebay has a bunch of used rotors for the XC. I'd make sure they are returnable if they are warped too.

I just had fixed the exact same thing. I also tried all the less costly fixes including brake cleaner and loosening those buttons with a rubber mallet. Unfortunately. it didn't work! What was explained to me that when the symptoms initially started it was because those buttons were not floating. If I were to have done the above fix then, it probably would had worked. As the buttons stay fixed longer, it warps the rotors. The only fix is to replace the rotors. What I didn't know is there is a decent supply of lightly "used" rotors out there. They come primarily off totaled bikes or those riders increasing the size of their front tires. Mine were ordered by my mechanic from a Victory Motorcycle post production designer. Unfortunately, I do not know the designer's name but that's where I would start looking. The part price was easily 1/2 that of new rotors. I hope this helped.

Something that I would never expect to be an issue. Nice to know all the little surprises like this that might come up.

Don't know if these are the correct size. There are replacement buttons out there and not hard to install
