Well I was digging through storage on the weekend and came across my now old new set of both rear and front brake rotors, picked up the box and the disk fell out and noticed that the cardboard had fused to the surface of the disk and it was rusty too….so I got to work on cleaning it, let it soak in water so I could scrape of the cardboard, and then my next concern was the rust as this had build up at least 1 -2mm…used wet and dry in a circular motion until I got it flat as possible….to touch you cannot feel any unevenness on the surface but when running wet and dry around the surface you get a different sound on the part of the disk that was most corroded leaving me to believe it is grooved? And if I stick on the rotor the same will happened when the pads grind over the disk I guess?


Question is will I have major issues here wobbly steering etc or judder on breaking or will the pads bed in and also wear down the rotor either way…..we are talking about the front end rotor here that does most of the stopping I guess as they are twice as thick at the rears …..but have stored em on their side now, and oiled em well…..
