Today on the way to work I was turning off on to a side road. I was braking going through the turn and when I came out of it I put it down into second gear causing the front tires to spin alittle(the roads were still alittle slick from last nights rain). As I was getting back up to speed when my Anti-Lock light came on but nothing seemed different. It had come on once before but reset itself after I turned the car off and turned it back on. This time when I turned my car off the light came back on. But ince again nothing seemed wrong, on lunch break I took it out for alittle and messed around to see if I could find any symptoms. At first it seemed like there was some resistance in the right front brake(the turn I went around was a right hand turn). I then went into an open parking lot(it is now raining and everything is wet) and threw it in reverse and took it up to about 30mph and slammed the brakes to the floor, they worked fine nothing locked up. I then put it in first took it up to 30 mph, slammed on the brakes and nothing, just a very impressive stop for the rain. On the way home from work I was messing around trying everything I could(fast acclerations, hard stops, sharp turns, tire spinning) just to see if I could get the light to go out.....nothing. When I got back to my house I took it up to about 55mph and slammed on the brakes, tires didn't slide just another quick stop. When I got out of my car I noticed a buzzing sound coming from my right front wheel well and a slight vibration through the brake pedal even when the car is turned off. I asked the local mechanic and he said when my tires spun going around turning off on to that side road it may have vibrated enough to knock one of the Anti-Lock sensors out of place. Is that possible? OH yeah one more thing. There use to be a nice vibration when I hit the brakes(warped rotors is my guess) now that this has happened there is hardly any vibration when I step on my brakes, even if I slam them to the floor. Might I be in need of new pads or rotors? Could this be something else? I know someone on this board could probably tell me whats wrong. I just need to find a cure. I can already feel my heartbeat slowing down. I love this car and want to take good care of it. Someone PLEASE help!!!!!
