Either 9mm hex or Torx T-45
The size is 9mm hex. It needs to be long enough to reach the recessed caliper bolt.
To remove and replace floating caliper mounting bolts. 3/8" and 8mm hex bits are used for General Motors vehicles. 7mm and 1/4" hex bit are used for Ford. 2003-2006 Ford Expedition use the 7MM hex bit. 7MM hex bit does not work on a 2006 Expedition. Looks like it requires a 9MM, the only one that is not included in my hex set. On a 2006 Expedition Limited, the front calipers use a 9MM hex bit while the rear calipers use a 7MM hex bit.
9mm hex
Bolt pattern is 5x135
no...the bolt spacing is different
Bolt Pattern: 6-135
5-135
Bolt pattern for what? There are a lot of bolt patterns. Mostly, Dodge and Ford do not interchange.
Bolt Pattern: 5-135
If your reffering to the tire bolt pattern then is 5-135
On most 2006 Expeditions, the front calipers use a 9MM hex bit while the rear calipers use a 7MM hex bit. 9mm hex bits are not easy to find as singles and will usually only be found as part of large metric hex bit sets. .
