You can buy the pads with new covers separately. Any of the suppliers of the whole thing should be able to help you.

Like Eddie I would like a source for the material.  My Performance brush is so old that replacement pads are no longer available.

When I was in Finland for the World Seniors a couple of years ago I bought such a recovered broom head from the Finnish Association - so you might try to contact somebody through their website to see what material they used and where they got it from.

You could try pvc backed woven polyester. It is commonly used as garden furniture weather covers, although the weave will be tighter and weight of the material will be less, but there may be other products made from the aforementioned that I haven't thought of that have a better weight and weave density and may make a more effective pad.

Also, make sure you put some tinfoil on the underside to reflect all that brushing effort heat back on to the ice.

I am getting way ahead of myself here, but I have recently returned from visiting a factory in China that makes curling brushes. The patents that the big names have make importing what is already being manufactured, difficult within Europe and USA/Canada, and since development is very expensive, we have very few alternatives to the current brooms and heads offered from the big players.  However, I am working with the factory on designing a new head that won't have a rigid plastic replacement pad or retaining screws, and it will (hopefully)  be cheaper to replace the pad on an ongoing basis.
