The other day it snowed here in Rochester and we did not get much snow but the roads got covered lightly with maybe a half inch of snow. I noticed that even if I just touched my brakes the ABS would kick on and work poorly by not letting me stop barely at all. I have brand new Power Stop drilled slotted rotors with ceramic pads I installed a month ago. I am wondering if it is my ABS sensors that are shot or so called (ABS Speed Sensors) that have failed. Any suggestions?
