Inquiry (采购产品): brakes Hi, I am wondering if bicycle brakes contain asbestos, as some car and motorcycle brakes? Have they ever, or do the bicycle brakes not heat up like the motorized vehicles? Can the new disk brakes be put on any mountain bike, or does one have to have different wheels? (I have an older rock hopper/specialized) Thanks for your help.
