R100RS (1982) worn discs
My nice & shiny front brake discs are worn and ridged, can anyone tell me what the wear limit is please? Actually, I'm pretty sure they need replacing, should I go for the cast iron ones (mehanite?) as sold by Motobins or what? Is it possible (and safe) to renew the disc without the carrier, the original discs are riveted on to the carrier and I don't fancy riveting cast iron to anything myself. Would high tensile bolts be OK? Will I then need different pad materials? PS Many thanks Grant for your by-return replies to my other three queries earlier today, I do have a few more, and I hope not to become a bore. Thanks again.
