Interesting info in that article Julie!

He's written loads and loads of articles, write ups, etc, etc. He's a bit of an arrogant so and so but I usually find people that have knowledge based on years of personal experience usually are.
If you look up Motorcycleproject. com there is loads to read. Whether you agree with it or not is a totally different matter of course.

There are amusing notes in there....

   "Brake squeal, whether disc or drum, is generally a matter of vibration."

  Well it's all vibration else you wouldn't hear it at all, therefore no reason to change anything  :)

McCabe-Thiele (Ted):
Are Cruzinimage the same as Crumage is it an abreviation?

I thought it has been well known that the rings are prone to wear quicker than original but not generally an issue as restored bikes tend not to cover the distances.

I wouldn't say that statement was true Ted, ALL rings should be fit for purpose and they should all be made of a metal that resists wear as much as possible. If the rings are wearing out quickly then it's false economy to buy them as the gaskets/oil etc that you need to buy to replace them due to the excessive wear makes them dearer not cheaper to fit. Not so bad on engines where you can take the barrels off in the frame but on a 750 for instance all that extra work is really something you want to avoid if at all possible.

Hence why I think members should be informed of the potential for this to happen, especially as good gaskets etc as getting harder and harder to find.

As for brake squeal, got to disagree slightly Nige, a lot of people think it's copper and other metal parts in the pad which cause brake squeal, generally I think because that's the noise they hear when they apply the brake, they change the pads and the noise goes away, which they think supports that theory but they miss the fact that they've also changed the backing plate at the same time and it's usually that which is causing the problem. Maybe he should have phrased it better, saying 80% vibration and 20% other factors? It's been well reported on here that chamfering the edges has worked, is that because it was the edge or just because they disturbed the pad doing it?

If nothing else he's getting people talking about these problems and possibly introducing other theories.
