In an effort to trace this obnoxious squealing sound coming from my
brakes when the brake pedal isn't pressed, I took my caliper off the
rotor.  Well, it appears that I have a Teves caliper.  Good start.
I take out the pads and can't find the noise damping plates.  The pads
were flush up against the piston.  And, the piston has these funky
recessed area in it for the missing damping plates which must have
been causing the pads to hit the rotor a bit off.   At some point in
the long, sordid history of my van, the previous owner's mechanic must
have dumped the noise damping backing plates.  I guess this is a
problem, right?  Everyone is using the caliper with the noise damping
plates, right?

So, can I just buy the damping plates?

Also, has anyone bought ATE calipers from BusDepot?  The price is
good, but the picture looks like it has only half of the caliper,
without the caliper housing??

I'm not sure if I'm using the terminology correctly, but there appears
to be two pistons on each caliper, one on the piece that bolts onto
the wheel and the other that bolts onto that piece.

Looking forward to hearing some opinions about these noise damping
plates and experiences buying calipers (versus buying the seals and
the backing plates in my case).
