I've just noticed that both of the front rotors on my '85 308 have numerous wear marks--as if the pads are worn out and rubbing has occurred. However, the pads themselves have at least half life left and I get no syptoms of any type, such as pulsating pedal, noises, etc. The brakes work and sound tip-top. The rear rotors , on the other hand, are as smooth and mark-free as can be. Is this typical--or do you think I have some kind of problem with my fronts. As I said , the brakes work great and there is no noise .
