That looks interesting. Is that a rear wheel in the picture? I don't have any
springs like that on mine, so I assume whoever replaced pads before me left
them off.
Dang goofball. I'll find some. That's likely the problem. Thanks!

The mass of the vehicle isn't what causes the rattle, it's vibration. The
hammer causes vibration. Mass has an affect on resonance, but I don't think
the whole 5,000 lbs. is making my brake pads rattle.
I think the guy in the previous post may have the answer.

My pads have that smooth plastic looking thing on the back. I still think it
may be the dampening springs. Thanks!

I wold be more inclined to think anti-rattle clips not installed on the
front brake pads correctly (or just gone all together) They need to be at
the end of the pad that the rotor sees first. Also don't go with cheep
brakes. I use Stewart Rittle <sp> brakes and they have eliminated any
comebacks due to noise or dusting, they also wear really good.

Great! That sounds like the fix. Another question: One end of the pads has
only one ear for contacting the caliper. The other end has two ears that trap
that end of the pad on the caliper. Which end goes which way? I have the
trapping end seeing the rotor first, which would be the end those springs go
on, Is that correct?
Maybe when I get some springs there will only be one way they go. Thanks.
