Floating Discs
#1
I was meandering YouTube and came across a video discussing floating discs and how to free them up with a torx driver, brake fluid and a twiddle.
In the 20 odd years I've had the bike, I've never done this. I had a quick look at the bike - too cold to give it more than a cursory look - I couldn't detect any movement.
Not wishing to fix something that's not broken I thought I'd ask the group.

Is this part of your normal maintenance and should you be able to detect any movement?

From what I understand, the purpose of the floating discs is to stop them warping when they're in heavy use (ie in racing etc) where they can get very hot.

I did free mine up a few years back by putting a nut and bolt through the "float" bits, then using something (might have been brake cleaner or a small amount of penetrating oil or WD40, I really can't remember off hand) to ease them so when I turned the bolt, it would loosen them up.

But I haven't done that again since and, frankly, if you've not had problems in 20 years, I doubt you're going to have issues in the next 20!

I certainly would not use brake fluid. I've always brake CLEANER. As Grahamm says, nut and bolt through the holees, nip it up, spray the ckeaner at the bobbin and work the nut/bolt around
