Note: It may be required to bang on the rotor a little to make it loose. If you plan on reusing the rotor be careful not to hit the shiny part.

Now that the rotor is loose.

**7** Take off the rotor.

While your there spray everything with some brake clean. Those smaller shoes inside the rear caliper are your parking brake shoes. Adjust while you are there if necessary.

Now grab the caliper and an old pad. Put one of the old pads back in and use it to even out the pressure put on the piston. Grab a pair of channel locks and squeeze the piston back in. You may have to do the either piston as you hold the other from coming out. Alternate between the two, you'll get it. It was easy enough that my son actually did it himself.

**13** Squeeze the pistons back in.

After the pistons are the ENTIRE way in slide new pads in place.

Don't forget to spray everything down with brake clean to get the film off of your new rotor.

After you wheel is back on you can tighten the lug nuts as tight as you can get them with a wrench. Put the car back on the ground and tighten them again.

**22** Time to wash up.
