you need to read the fine print on maintenance agreements - brakes are a normal wear out item that they USUALLY don't cover. (similar to bulbs, wipers, tune ups & oil changes) they usually cover engine parts, transmissions etc. I'd go over the agreement with a fine tooth comb & find out EXACTLY what it covers - have them(dealer & service dept.) underline exactly what it covers then you'll be able to decide if it's worth your $$$ - be leary also, ALL dealers do NOT honor other dealers extended warranties - they're aftermarket insurance companies and not actual BMW warranties and they vary from dealer to dealer.
