ABS Brakes shudder
 
NO ABS light, but when I'm approaching stop (somewhere from 5 mph down to 0 mph) I can feel the brake pedal "shudder". Also, if I'm turning hard while slowing, the (ABS?, power sterring?) makes a terrible noise like hydraulic pressure relieving somewhere??? Rotors are good, pads are near new front and back.

Resolved!
 
Thx, swartlkk !!! The info in the link did the trick. I had been having the problem even before I replaced the right front wheel hub assembly. The old sensor cable had a big hole in it - like a piece of molten metal, well, melted through it. However, since the wheel hub assembly came with the sensor I didn't use the old one. I then measured the ouput voltage from the new sensor - which was a fraction of the output from the left sensor. I removed a couple sensor shims and retested. The voltage was now at least in the ballpark with the other sensor, giving a more balanced input to the ABS system.

Thanks again!
