It's a regular 6 cylinder taurus, not the racy "SHO". I may have messed up the torx pattern in the bolts with an allen wrench. I was trying to get the bolts loose with a 3/16" allen wrench. Although I encountered resistance to turning with the 3/16" allen, upon struggling to break the bolt loose the allen started turning easilly and I may have rounded out the star pattern or torx pattern for the correct size torx driver. Any idea what the proper size torx to use on the caliper bolts is? Thank you.
