Hi David,

Other than a binding brake I have never heard of this.

The only thing that can cause it to melt is heat so where can the heat come from, Brakes or bearings (unlikely). So if you go for an enthusiastic ride, is the drum warm ?

You say the brakes are not binding as you have backed them off but is it possible it sometimes stays on after you have taken your foot off the brake ?

Keep us informed of your findings

Regards

Tony

Go for a run and check the hub, is it hot? Does your foot hover over the brake pedal?

Years ago, I've noticed the same mistery.

The brake cable was a little to short so on every additional deflection during the ride the brake shoes touched the drum, et voila: the drum becames hot enought to let the cush drive buffers melt.

I've replaced the cable with one from the usual suspects.

Is your rear brake cable routed correctly i.e. over the z plate. routing it below will result in it being applied every time you compress the rear suspension.
