it was all working fine before. when i had this problem in the past i just cleaned the hubs and sensors and it worked. the car has not been driven for months and when i got it out the light will not turn off. the brakes feel fine tho.. so i cleaned the hubs and sensors replaced the bolts and still not working but i think i pushed one of the rear sensors in too far as it made a noise when the wheel turned and ive now seen that ive broke a sensor..
