Frank,
I uploaded a sketch of the pads. I do not know what they are make of. I do have images of the pads, but the site will not allow me to upload them. If you have an email address or cell phone, I can send them to you. The brakes are from a midget that was probably built in the late 1950's / early 1960's, if that helps. Thanks in advance, please call or respond to this ad if you need any additional information.
Thanks,
Gary Moury
