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?"
Should be 10mm or 3/8ths Actually, it turned out to be 7mm Allen wrench.
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?
To effectively loosen a brake caliper, you can use a wrench to loosen the bolts that secure it in place. Make sure to support the caliper to prevent damage to the brake line. Once the bolts are loosened, gently wiggle the caliper to remove it from the rotor. Be cautious not to damage the brake line or other components.
I believe that may be 7mm Allen.
7 mm Allen wrench
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.
Metric Allen wrench.
