Re: 88 5KQ grinding sound from ABS - Normal?

[audistuff@juno.com (Paul R Anderson)]

I have the same grinding noise on my 87 5kq.  I think it's better since
I replaced a bad left front wheel bearing but it still makes the noise
and the feeling in the pedal.
I'm looking forward to hearing from the list on this one.
