Abs tone ring question

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

Welcome to the forum

Yes, the missing metal can cause incorrect reading of each tooth as it passes by the sensor, so ABS thinks that wheel is spinning slower than the other wheel and is try to prevent it from locking up
