So I was following on of the guides in the garage to change my pads and rotors. It said to put two bolts in the old rotor when remove and tighten them to pull out the old rotor. I already took out the two screws. But This ( picture below) fell out when I was tighten the two bolts to try to remove the rotor. First, What is it, and do you have any other tips on removing the rear rotors. I got the other sides fine. Thanks in advance for any help.

Looks like the Bolt/Clip for your parking brake. Need to put it back on. There should be a spring and some sort of locking cap that should go with it as well.

 

It is the retaining clip for the park brake shoe. These a fun to install, you probably need the clip that goes with it. I replaced all the park brake parts in my car a few years ago, it took some patience to say the least.

 

valve?

 

Thanks guys. I replaced the pin because it was too damaged to be used again. But no I have a new problem. When I go in reverse and back up I feel like the parking brake is engaged. I feel the car will stutter at times when reversing. Any advice?
