I just changed my front ones last night...It takes an 18mm socket. I used a 1/2 in drive so as to get as much torque as possible on the breaker arm to remove rusty bolts. It took a little doing and the help of some penetrating fluid.
Loosen and remove the caliper retaining bolts. Torx T-40 or T-45
7mm Allen wrench
9mm
I believe it is a 7mm hex.
What kind of wrench is needed to loosen the oil filter in a Mercedes Benz ml?"
For the caliper mount bolts that are removed during a brake pad change, 1/2" is a good fit on my 1996 F250. 13mm will fit but is a little sloppy. Were you asking about the "caliper bracket" instead?
Should be 10mm or 3/8ths Actually, it turned out to be 7mm Allen wrench.
I believe that may be 7mm Allen.

The calipers need a 7 mm hex wrench. The Caliper holder to remove the rotors takes an 18mm socket. This is a 2003 Ford escape..apparently it's the same as a Mazda tribute.
You need a 15 mm regular wrench.
Metric Allen wrench.
