i just changed my front rotors and pads on my 2001 escape, 6 cylinder. everyone was wrong on the wrench sizes, including the idiots at my local Ford dealer. to get the brake calipers off I needed a 7mm hex bit. to get the caliper bracket off I needed an 18mm socket, it was a very easy job but check your wrench sizes first, it seems that every year and model uses different sizes.
Not likely to be Allen key, try 15 mm regular wrench
2006 lincoln navigator requires a 7mm hex to remove brake caliper
3/8"
It takes a FA12A Allen wrench.
A 3/8" Allen wrench will remove that bolt on the front caliper.
use an Allen wrench not a socket or open or box wrench.
Depending where it was built, a 3/8 Allen key or 15 mm regular wrench.
I believe a 3/8 Allen is the right tool.
"Caliper anchor bolts" hold the brake caliper on, they require a 3/8" Allen wrench to remove.
Remove wheel, remove the bolt holding brake hose to the caliper, remove the two pins that hold the caliper to the caliper bracket using a 3/8" allen wrench, remove caliper. Inspect brake pads and brake hose for damage, replace if necessary. Install new brake caliper in reverse order. Bleed system.
I believe that one is 3/8 allen wrench, but it takes about 5 minutes to check so you should make sure.
it is an Allen wrench not a TORX socket
