Here are the pics that display the result from using EBC red stuff pads with EBC rotors on my car for 3 months(front and rear) The sales guy said it might be caused by the pads or malfunctioning brake piston so the rotors are not under warrantee, but the mechanic said the caliper is working perfect and he is 100 percent sure it is caused by the material of brake pads. I emailed EBC three days ago, but have not recieved any message yet.

 

I have this same set up and havent had any problems with it. I really dont know what to say. I sell tons of EBC stuff and havent seen a problem like this before. I am really hard on my brakes and they work perfect. Guess you got some bad pads.

 

Looks like a rock got stuck in there, do you do a lot of driving on gravel or dirt?

Have you pulled out the pads to see what they look like?

Could your mechanic explain his reasoning, I'm curious.

Wow interesting how your rotor looks like that. I have the same set-up and have not seen that on my rotors. Maybe something got jammed betwen your pads and rotor as hypersprite stated.

 

Agree. Interesting how the line dissects the center of the holes perfectly. A bit of foreign material got stuck in the hole. The pad picked it up. Now it is embedded in the pad.

 

The mechanic pulled out brake pads and nothing was stuck in between. Both sides of the front rotors have the scratch lines. I have EBC red stuff pads in the front and metal master pads in the rear. Apparently the situation in the front is a lot worse than the rear.
