Well they have been great thus far and now I have steering wheel wobble when i apply 40% or more brake at speeds around 30-70mph. Someone told me that it could be carbon buildup on the rotors making the surface uneven and that some heavy braking could help burn it off? Any suggestions on what I should do. Ive contemplated buying new brake pads to see if that will change anything. Thanks for any advice.
Sounds like you didn't properly bed the pads to the new rotors. Depending on the pads, the procedure may vary a little but the general concept is to do a series of 60 - 5 MPH hard stops with a few minutes of driving (while minimizing the use of the brakes) in between to let the brakes cool down. This ensures an even transfer of pad material to the rotor to prevent brake pulsation at high speeds.
