ABS Not Working?

[George Harris]

I recently purchased my '87 5kcdtq. The Anti lock wasn't working. Had to
tear down the front end for other work, so while I had everything apart
I cleaned up the loose rust on the ABS pickup teeth and painted with
some paint that is supposed to bind rust and stop it from spreading.
Also cleaned all the rust and metal flakes off the magnetic pickups.

ABS works now.

Cheers
George
