I'm currently working on replacing my rotors and brake pads for the rear of my mazda 5. I'm having trouble putting the inboard(inner) brake pad back on there is a spring that goes on the outside of the caliper. i believe its called an anti-rattle spring but i could be wrong. it appears to hold the inboard brake pad tightly to the caliper. I'm not sure how to put this spring back on. Help would be appreciated. thank you.

 

Easy one!!
I use needle nosed pliers to reinstall that spring. By its nature, it is springy, so install one side of the spring into its final resting place (hole) and grab the other w/needle-nosed pliers and pull it into the other side. DONE!!
But also keep in mind that the rear calipers have a "screw-in" pistons and if you do not do this when replacing the pads w/newer, thicker ones, will not be able to get the caliper back over the rotor.

 

if anyone can provide pics of this that would be awesome... happy holidays to everyone!!!
