Can someone explain what is exactly involved when cleaning brakes? I have replaced brake pads, calipers, brackets for the last 10 years (thanks to owning a Grand Caravan!). I have never cleaned the pads. Pads should always be replaced (they are relatively cheap). Rusts on the brackets should be filed off, pins should be lubricated with lithium grease, anti seize grease on bolts and the backsides of the pads.
