Whagwan wi me rear brake an ting?

[Cigaro]

The rear drum brake on my Cub seems to have an intermittent problem - occasionally (well, about once a day on average) when I put the brake on it makes a horrible 'Grinding' noise, like when you try to put a car into reverse when it's moving. If I let off and apply it again, it doesn't make the noise, and it doesn't seem to affect its stopping ability - overall the rear brake seems quite effective.

Pray tell, what could the problem be?

Well, it might have a stone or something in there.

The shoes sometimes wear unevenly too meaning only the front part of the pad touches down on the drum. This can be cured by putting a slight chamfer on the leading edge of the pad using some sandpaper.

Given how a C90 has a quick-detach rear wheel which takes all of 2 minutes to remove, I'd suggest you whip it off and have a look.

My A100 used to do that the first time you applied the brake if it had been stood outside in the pissing rain all night. Tis rust on the friction surface of the drum which is scrubbed off when you dab the brake.

Could be a touch of water in the drum. Wet brakes slip but damp brakes can grab and judder.
