Brake pedal vibrating at a stop

And... a few days later it's back again. Is there a way to check the signal from the controller behind the radio to the solenoid and see if it is sending a signal causing the abs to kick in incorrectly? This seems to be a relatively simple system that shouldn't be that hard to fix. Esp. Since most parts of it have been replaced.

I noticed today after rebuilding the back brakes with new drums. Shoes, and hardware- this only happens under 5 or so mph and the speedo bounces at the same rythym. Seems like a signal issue. The only parts left to check seems to be the wiring connector on the vss and the tone ring.

After all this time, I finally found the source of the problem. After noticing that there was axle fluid leaking, I tracked it to the o-ring on the vss sensor. Didn't want to dig for a workable o-ring, so ordered another VSS. Installed it and bingo. Leak stopped and vibrating pedal/bouncing speedo fixed. So either the two previous vss sensors had an issue, or something with the connector.
