Can also cause a hot spot on the rotor & lead to rotor distortion).

Ok this has made some sense I have a couple of marks on the rotors and for the life of me didn't know what they were, resin deposits is what they look like (I will take a photo after work). I dont brake that hard but do get caught in a lot of traffic to and from work. I don't use the handbrake and yes leave my foot on the brake pedal. So yes it could of caused a hot spot.
