I bought my car in July and I am pretty sure the breaks were done and then when my car was hit in October on the street, the mechanic that fixed my car did the back breaks. I come home from college and the ABS and Break lights stay on. I brought it in and they said it was that the brakes were fine as far as they could see and that there was some sort of blockage in the rear abs and I would have to go to a dealer to get it fixed. What does this mean? I have to drive a far distance over a moutnian this weekend will I be ok? The breaks seem fine!
