Hi, I am just wondering if anybody uses ceramic brake pads? I have a W204 C220 CDI and I am getting a lot of brake dust from the pads that were fitted before i bought it. I believe ceramic pads give off a light grey dust that isn't prone to sticking to your rims but I also heard that ceramic pads need time to warmup for optimum braking. This concerns me as I don't want to compromise braking power on a cold start. Any advice would be greatly appreciated.
