I've had the PBR Deluxe on my 560SL for at least three years now (can't remember if it's 3 or 4). They DO stop just fine, even in the rain, and DON'T seem to cause any inordinate rotor wear. They DO cut down the wheel cleaning from every 1-2 days to every 1-2 weeks, and make it a lot easier when it does need to happen.

There are a few things about traditional Mercedes engineering that seem to come from the department of "Of course, zis is a problem, but it is ze best. You vill liff viss ze problem because it is our way." Brake pads that shed an obscene amount of dust, when there are eminiently satisfactory alternatives, seem to be one of those. (But then the ultimate in that regard is Ettore Bugatti, who when a customer complained about his car starting hard in cold weather, retorted, "If you can afford a Bugatti, you can afford a heated garage!")
