Brake Blocks Damaging Rims
Took my new wheels (see: http://www.eastonbike.com/PRODUCTS/WHEE ... st_II.html) out for a 35 mile blast this morning. A short while into the ride the when I applied the brakes the brake blocks started to make a horrible grinding noise on the rim. This was worse on the front. Luckily I managed to get home without having to use the brakes much (quiet country roads). When I got home I took the brake blocks off, they seem to have small bits (flakes) of aluminium embedded in them!! I assume that this is what is causing the horrible grinding noise. The brake blocks are Shimano. What's going on? There must surely be some issue with these brake blocks?
