Well, call me stupid, but can anyone tell me why all the older red compound brake pads were formulated with what appears to be cotton threads mixed within the rubber?

Universal pads in particular seemed to have a high "fiber" content.

Perhaps for steel rims? For wet weather? To resist abrasion?

I can imagine countless reasons, but can someone site the real intended purpose?

Thanks!
