Turn the piston all the way in. It will settle to a postion where it no longer goes in, it is just you turning it.

Then, place a piston jack in the caliper and push the piston back as far as it will go.

Place both pads into the caliper and measure the distance. Check this distance to the rotor. There should be a small difference between the two.

Now, to get the parking brake to work, turn the piston out until it rubs when the caliper with the pads it put over the rotor.

Once it will rub, you should be able to turn the rotor with a little friction. Turn the rotor with your hand and push the parking brake lever. the rotor should lock 1/3 the way in.

Do the same to both sides.

Hope this helps
