Hey everyone I thought I'd see what your bikes were like. My front brake rotor is loose. I don't remember if it was like that before. I've been looking around and can buy a new one, but I have a couple problems with that.
1. The rotor is fine and doesn't need replaced (except for being loose)

2. The replacements seem to be 5 bolt hole replacements, but mine has 9 bolts holding it onto the carrier.

What about you guys? Ever run into this problem?

The rotors are "floating" rotors and are supposed to move and be a little "loose". Can you take a pic or describe this problem better?

You have the newer style front rotor. The older style had 6 buttons holding the rotor to the carrier and were rebuildible. The new style was offered on 2000 and newer tube framed bikes. When did you get yours?

The older style seemed to rattle more, I haven't had any problem with my new one. My spare wheels have the older style, but I haven't mounted them yet, so I can't say anything about them.

I'll try to take some pictures. I did find out that I do have the newer style rotor. I bought the bike used 2 years ago.

Where it's loose is at the 9 buttons. Everything else is tight. I understand that it's a floating rotor. Is it normal to replace it because it's "floating" too much or because it's gets worn. I haven't been riding it because I thought the rotor was bad.

You should get movement, but it shouldn't rattle like the older ones do.

There is a limit to the amount of movement allowable for safe operation. I can't recall the exact spec, but the service manual shows how to measure it.

I could get back to you on it.

I've been outta town and just went over to my dad's (where the bike is parked) and took a look at the rotor's again. They're the old rotors. There's a considerable amount of play. Can that be rebuilt? Is it best to just get the new rotor? Is it difficult to get those rotors off? I tried to take the rotor off of my rear tire and failed miserably. I can't seem to find a good shop around here to take my bike to.

Seemingly a lot of play is pretty normal for the old style. They are rebuildable, but most people just go with a new rotor (newer style or aftermarket by EBC or Braking, both aftermarket ones are cheaper then the OEM).

The rotors are loctited on with some pretty strong stuff. Heating up the bolts and giving them a pretty good whack with a hammer should break loose the loctite. The rotor bolts should be replaced, they are not reusable.

Just ordered the EBC Race Brake Rotors from American Sport Bike. Anyone else have these on their bike? They seem quality and they were the cheapest there. I can't believe it's been so long since I've been on my bike......I'm dying here.

From everything that I've heard, you can't go wrong with them. If their pads are any indication, great quality. Also Gary at EBC is very accessible, and they really have that small company that cares feel to them.

Got my new rotor today. The only thing I need to do now is get the old one off. Which is no small job. Anyone have any suggestions? Those suckers are usually pretty tight.

I've heard of some nightmares, but mine just screwed right off with no problems.

Try that first.

As for getting the old bolts off, a heat gun and one of those small handheld impact drivers work wonders.

I started pulling those freaking bolts out last night, no luck. I PB blasted those things. We let em sit over night. Al at American Sport Bike said he always had to weld nuts to them and pull them off that way. Anyone else have any creative ways to get those rotor bolts out? It would be great to get that thing on the road soon. I'm itching to ride.

Zenfrogmaster had a great suggestion with the heat and hand held impact driver.

Just be careful with the heat if you use a propane torch.
