It has been several days now with the ABS disabled and I have no more grinding, brake release symptoms. Just a yellow ABS light on all the time. So now do I fix it or put electrical tape over the idiot light. I live in AZ and am not likely to be driving in snow or even rain for that matter. Decisions, decisions... I still think it has to be the front left sensor making the ABS think the left wheel is locking up and thus releasing the pressure accordingly.
