With duct tape......

The car might be a little harder to do. You didn't say what brand you
used, but I'll give you the benefit of the doubt and assume you used a
premium, higher quality pad like Wagner or Raybestos. (The el-cheapo
lifetime-warranty pads from a national chain store are crap) You also
want to make sure that all anti-rattle clips or springs are up to spec
and in place. Your '96 Mustang may not have any of this, but I'm
speaking of all applications in general. If none of this helps, you
will need to have your rotors turned or replaced to get rid of the
squeal. And once again, don't put on cheap Chinese made rotors. They
are crappier than the cheap brake pads.
One last comment. This is not a plug for Ford or Motorcraft brake pads,
but if you have brakes done at a dealership, they will simply put in
new pads without turning the rotors and chances are they will not
squeal. I'm only saying this because there is a difference between
dealership parts and national chain store parts.
My $.02 worth.

lmfao
they need more braking in
lmfao
a tard does the brakes i feel confident
face it brakes have to  and are more powerful than the engine
look at the energy they have to stop

imo
if you dont understand why they vibrate
DONT WORK ON BRAKES

you foctard

   Disc brake squeal is caused by the pads vibrating
in the calipers, particularly the outboard pads.
Ceramic brakes squeal, but at a much higher frequency
so we don't hear it.  I wonder of the dog can?
    Anyway, the fix is very simple and cheap.  Go to
the parts store and get a package of Disk Brake Quiet,
by Permatex.  It's like glue for the calipers.
    Take the pads off the calipers, and clean all the
mounting surfaces really well.  Use a wire brush and
some brake parts cleaner.  Spread a little of the blue
gunk on the mounting pads - you don't need much.  Then
assemble, apply the brakes once or twice in the garage
to seat the pads, and let sit overnight.
   Voila!  No more squealing!
