How do you compress the rear caliper piston on a 2005 Ford Mustang?

Go to Harbour Freight tools, or ask Autozone if they have a Brake Caliper tool, AND DO NOT BUY THE CUBE OR BLOCK- it is a pain in theButt, and will take you a year to compress the piston.Buy this: http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=40732
It will get the job done fast and easy!!!!

I have been using the cube tool with a 3 inch extension on an impact and it has worked very well for many years. It is fast and easy for me.
