Let me start off by saying I have a 2011 ford ranger with disc brakes all around. I decided to do a brake job as in replacing pads and rotors. Did the fronts first, broke in the brakes and everything was fine. Then I did the rears including the little drum brakes inside the rotor for the ebrake. After putting everything back together I noticed a grinding sound from the rear passenger side wheel and a pulsation in the pedal. Tore everything apart and realized I had installed one of the springs for the ebrake wrong and it was dragging along the abs tone ring wearing a small grove in it. I fixed the spring and the sound went away but the pulsation continues. I took it to a shop that said both rear rotors were warped. My question is should I just replace the rotors or could this wear mark on the tone ring be causing my issue. Thanks in advance! I should also add that their is no abs light or any warning lights on the dash
