Thread: Wheels - Brake Drums.......

I think it happens to all of us.
Does it really matter?

coppa-slip? thin rubber/cardboard gasket?

I agree. Probably help to ensure the paint on the wheels is thoroughly dry and if you are really fussy polish the brake drum face and apply a thin coat of gloss heat resistant paint - and make sure this is dry as well.

But does it matter?

I didn't think some of the ideas in these posts were good so I checked with John

Here is a copy of the message I sent to him and his reply

There is a post in the tec section about paint loss from inside wheel.
Now I don't know how to explain this but I thought that the drive from the axle to the wheel is via the hub brake drum/disc being clamped together with the clamping force supplied by the wheel nuts/studs
Not through the studs and nuts
I don't think thin rubber gasket behind the rim is a good idea.
You explain thing like this far better than I ever could,and I think things like this should be set straight.

Hello Jim,
Friction from the clamping force provides the majority of the drive.

If the clamping force is insufficient the wheel will come loose, drive would then be via the studs, through the bolt holes, until the inevitable happens, the nuts progressively loosen and ...

A rubber gasket behind the wheel is a very bad idea. The theory is complicated to explain simply with words. Doing this will most likely result in loose nuts, with a great chance of broken studs.

Good friction clamp on the drum explains why the back mating face of my alloys have a purposeful looking grain, not smooth.

Good info.

Looks like you will have to find the right paint and application technique if you are going to beat the peel! Or try and find something else that needs doing

Happy hunting.

A smear of grease should do the trick.......but make sure the paint has fully cured/dried first......overnight is not really long enough......may need to sit in te sun for a few days to dry properly.....
