need brake part name .
 

2000 E430 4 matic, I'm trying to find out what this part is called, it's the spring/strip on top of the caliper in the pic that is kind of holding the caliper through the two holes...
thanks. :)

In american car speak, it would be called the the Brake Caliper Anti-Rattle Spring.

thanks ok and the purpose for this is what ? keep the caliper from rattling ?. hmmm.

It's to keep the pad from rattling, from what I understand.

The way the w126 cars have it setup, it's wedged in against the edge of the pad, and helps keep the pad forced against the caliper body. Again, if I understand it correctly, it should help keep the pad from jolting to the side when first applying the brakes, and may help to reduce brake squeal.
