Floating disks - at risk of floating away completely?

[ldnz]

Hey guys,

Just picked up a '90 GSX600f as a temporary ride and despite it flying through a warrant (at VTNZ, not the local shadies), i've found a problem with the front brakes.

Riding around at low speeds the bike was making a bit of a plasticy bump noise like a piece of loose fairing or something and I eventually traced it to the front left disk, which is loose on its rivit thingies.

There is a bit of play in the disk, ie you can grab it and shake it around enough to make it rattle, which i've never seen before. All the rivits are loose, theres no obvious other problems or reason for it, the brake caliper seems to be in line etc. Its also only on the left disk, RHS is sweet as.

So - is this a problem? It doesn't seem like the disk is gonna come away or anything, and I can live with the rattle. Or is it possible to replace the rivits with some new ones. The disk is otherwise in good shape, and given this bike cost me stuff all I really don't want to spend big money on it.

Looking forward to you thoughts.

Only thing I can think of that would cause it would be pistons sticking on one side of the caliper, continuously pushing the disk sideways?

Anyone got any thoughts? Possible solutions?

You'll have to investigate what has worn out, it's either the rivets, disc, or carrier. Discs are dirt cheap these days, if you're in doubt, give it the flick. There's a number of bike shops in Auckland, any of those should be able to give you an expert opinion on the suitability of using that disc in the future.

Worn rivets will become a safety issue and you should look into it sooner rather than later. If the rotor is still in good nick then you may just be able to get someone to re-do the rivets. Try F1 Engineering in hamilton (you can send them away).

Cheers. Just had a chat to the local warrant dude, and while he said they aren't instant screaming death, they don't want to get hugely worse. So im on the hunt for either a really cheap set (or single!) of gsx600f disks, or theres the possibility of just tightening up the rivits on a press.

Just buy a new one, they're not expensive.
