Gave my car its regular wash and I have to say that I'm mighty impressed with the way the ceramic pads have preformed with the smallest amount of dust they produce - very slight whitish dust that comes off with minimum effort - just wish I could justify changing the nearly new rears to the same ceramic pads plus getting rid of my rusty looking hubs on the rear discs - only surface brown but they catch my eye now the fronts look so good - toss up between the cost of new Zimmermann discs or the cheaper but more fiddly option of removing and painting.
