Metal in pads, how concerned should I be that the rims are damaged?
Hello:
My Surly LHT (stock build) has about 3000 miles on it, and I am quite ashamed to just now have changed the brake pads. The picture shows what I found on the existing pads. These were the stock Tektro pads and I have replaced them with Kool-Stop salmon pads.
In examining the rim, it _seems_ to have plenty of brake surface left .. .in fact I cannot see where this metal came from. How do people measure the amount of brake metal left on a rim?
Thanks for any hints.
