Turns out 1 of the replacement rotors had a bent sensor ring! these rings are pressed on to the backside of the hub. measuring from the back surface of the rotor to the sensor ring in several places (6) I came up with a difference of .075". (first check days ago was only in 1 place) On my old stock rotors all measurements were within .010". Checked the other replacement rotor all within .010". Went back to the parts store, they had 2 in stock, measured both of them 1-all within .020" the other all within .010", took the better of the 2 put it on, brakes work perfectly. So heads up to anyone replacing rotors, check the all the measurments! especially to the sensor ring! I used a depth mic & a ground parallel (to span the rotor) Also you could use a dial caliper & a parallel. Glad to have the brakes working properly again! Thanks again Bob, you pointed me in the right direction!
