Lost the spring for brake pads that pushes the wire
 

I lost the wire springs that go on brake pads , I didn’t know they were important. Drove off and my car was sounding like it’s dragging against the rotor. Can someone tell me where I can get the little v shaped thin wire springs that clip on the brake pads and push them out , they go in holes ? Also I think the pads I bought don’t have the holes where they will actually go in properly I bought KFE KFE1222-104 Ultra Quiet. For the front , what are those wires called and where can I get them in the Morning ? I’m worried if I can’t find them I gotta get entirely new pads cuz they are making noises. I also noticed the pads I took off had a little round clip at the bottom of them and the ones I put on didn’t. I shoulda bought the hardware with them , does autozone sell hardware for the es350 ? Thx guys

It is called the spreader spring or the separator spring or anti-squeal spring. There are 2 on each brake. 4 total.

Rock Auto sells a Centric Brake and a Raybestos hardware kit with those springs for under $10.

If your pads lack holes for the springs, return them and get some Raybestos Element 3 (EHT 3) pads at Rock Auto. They are great and inexpensive I have them on my RX and my Niece's ES350..
Rock Auto sells the pads with the springs and all other hardware for $35! https://www.rockauto.com/en/moreinfo...t=1684&jsn=943

Go here, there are hardware kits that include the anti-drag springs
