Does anyone know if the ABS can be shut down by pulling a fuse. I believe my
chattering brakes happen when I apply a fair amount of pressure to the
brakes above about 30 MPH. This problem started right after I had someone do
a brake job (all 4 wheels).
Thank you

If the fuse doesn't control anything else, it will.

Altough I don't like ABS myself, why unplug it instead of going back to
the shop where the brakes were done?

If I'm right I will then have an advantage over the shop if they want to
hand me another bill.

If you don't trust the shop, why did you go there?

If the concern wasn't evident before the repair, it shouldn't be there after
the repair..... much is going to hinge on what the RO that you signed stated
as a concern....

At the same time, you guys in the states do have a hard time with
charlatans.... Guys with a $99 Sears tool kit can open a shop and call
themselves automotive techs with no knowledge, no experience and no
scruples.

FWIW, I have seen a few vehicles where the finish on the rotors after
machining has resulted in an un-nerving noise and feel.... possibly akin to
the chatter you are feeling. These sorts of concerns I usually associate
with poor shops...... especially since any brake repair deserves an
extensive road test to both seat in the new friction surfaces and to ensure
that nothing has been overlooked....

Try seating or "breaking in" the brakes. See:

It is a mistake to disable you ABS unless you are just doing it temporarily
for diagnostic purposes. Many ABS systems depend upon the ABS to provide
front/rear brake proportioning. With the ABS disabled, you are more likely
to lock the rear brakes and that can be a really bad thing.

You did not mention what sort of car you have. It is unlikely that the ABS
would be the cause of your concern unless one brake is locking prematurely.
It seems more likely that the shop damaged a rotor by
unnecessarily/improperly turning then, or that the brakes were not properly
bedded in after the new pads were installed. If you do a hard stop with
"green" brake pads, it is possible to transfer lining material to the rotors
and this will result in chattering of a sort.
