The tool should have a square hole opening to put your male ratchet opening in
If you are looking at the side which will touch the caliper it will look like 4 raised dots
on it to catch onto the rear caliper gear
You might need help for someone to hold the caliper while you turn it
or turn the caliper a certain way to catch and hold it on the car
Be sure to take off the brake fluid cap when you do this
You will have to turn it down pretty far and when you put the pads on
Look for the dot on the back of the brake pad and make sure it goes into the notch of
the caliper gear so they are in well
