TonySz I just took the old pads out and put the new ones in. It really wasn't much different than my non ABS Camry. After I did the job the ABS light came on twice after I drove the car for a few miles. My CD said I either got crap on the sensor or left to much play in the wheel bearings. But after those two times the light never came on again.
So when I change the caliper bolts in a week or so I'll check everthing out. But my gues is some junk got on the sensor and than worked it's way off.
