I have a question concerning my front brake rotors on my 74 T/A. Each rotor has a groove perfectly placed in the center of the rotor. It looks to good to be worn by bad pads. The shape of the groove V-shaped as well. Is this an early attempt by Pontiac for vented rotors or are they just bad?

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
