Brake rotor question

[100thflht]

Okay, first question since coming back to the forum.
I'm putting 83 Wheels on my 82 and in the parts schematic it shows like a gasket material called vibration dampers between the disk and the wheel. Front wheel only. The parts are no longer available. Question, should i make ones out of gasket material or do I really need them and just install the rotors directly to the wheel.
Thanks in advance if anyone knows.

I don't know.

But..... I would probably make one from the thinnest gasket material I could find

I never heard of that. My concern about spacing out the disk is how centered in the calaper it was. I have seen thin paper between the disk and wheel, but none of my bikes have them, and my brakes don't vibrate

[100thflht]

Thanks for the responses. I wonder if it has anything to do with the 83 rotors being ventilated. Anyway, I'm just gonna install them without the material. I'm using the 82 rotors.
Thanks again.

Let us know how it works out, I'm interested.

[100thflht]

Thanks, I will. Gonna be a while though. Bike is down to the frame currently.

I have seen that on some of the CB900 CB1000 DOHC series bikes I restored in the past. It is quite thin material so a thin gasket material should be ideal. Usually a grey colour from what I recall.

I was thinking it was some kind of dampening shim so I looked on a Partzilla parts diagram & sure enough it is listed as a dampening shim. I have an 81 CBX that also has the vented discs ‘and surprisingly I redid all that many years ago and like you one of those basically fell apart so I just left it out, they weren’t available then either, what purpose could it serve ? Right ?

So,,, I’ve had a squeal in the front brakes off & on now for 25yrs, I’ve changed pads from oe Honda to EBC, Feroda and no real change in that squeal,,,,,hmmmmm. Maybe that little paper shim actually does something ?

At risk of sounding pedantic, "dampening" means making something damp (moist or slightly wet). Reducing vibration or oscillation is called damping.

I don't think that your statement is an example of an ostentatious or arrogant display of learning. Accurate terminology is important. Thanks for the clarification.

I have had 83 wheels on my 82 for decades and over a hundred of thousand of miles, nothing between the rotors and hubs.

82 rotors on 83 wheels and Metzlers of course..

Must be a Canadien thing,,,, ehh ?

Was working on the 1200 today and noticed that there is something sandwiched between the rotors and the wheel hub. Looks like a piece of thick paper. Parts book calls it SHIM, DAMPING but this may not be the oem part on here.

That's about all it is, thick paper... my '82 had it, I think the first year. It's nearly impossible to remove in one piece...
