Ok so this is my first brake job. I have completed the entire front end, but the rear is giving me fits, I have Napa brake pads, that came with no hardware to hold the pad on the caliper, I have the original one which is like a c with a hook on the ends kind of thing. But do I have to reset the caliper all the way in or how?

 

I think the c thing you are talking about is the clip that sits on the bottom of your brake calipers,this clip helps the brake pads line up right.

 

Just make sure that you push the piston all the way in.

 

Which rear calipers do you have? If the iron Delco ones, the piston must be wound back in, not compressed. The rear pads don't use a clip.

 

Be careful when you push or wind the caliper back in, the master cylinder will over fill, if you crack the bleed screw a little as you push the caliper in, it won't over flow the master. When you bleed the master cylinder, when your finished, if its a used unit, don't let the brake pedal go all the way to the floor, it can damage the cups inside.
