I am encountering more and more brass plated steel rivets when relining brakes, You can't tell them from a a solid brass rivet by looking, so check your rivets with a magnet. The steel rivets will destroy your drums, I know this for a fact because of 2- $800 drums in my International 500. I think that it is just rotten to put these things on the market, dishonest is more like it, more than likley Chinese garbage, the brass plating is meant to deceive. The price for the lack of solid brass rivets can be very expensive indeed. Check them-----don't take somebody's word for it, buy genuine Cat rivets. Tad
