So we don't use the brakes that much but I'm having a issue. Every time when we go to leave the house when I put it in reverse the car makes a loud clunking noise. After the first initial moving of the car it doesn't happen again until the next day or two. The rotors have a light surface rusting (more like a film of tan dust) in the brake area of the rotor but the rest of the rotor is rusting pretty good. It is way worse if I wash the car in the evening and don't drive it for a day or two. Unfortunately I don't get to drive it all the time so if it sits for two or more days I really have to put the pedal down for it to move. Anybody have this going on
