What tool is used to remove the front brake caliper on a 2007 ford expedition xlt? It looks like either a hex or torx bit but I have tried up to 3/8" hex and T50 torx with no luck.

The front caliper takes a 9mm hex drive socket, and you can order it from Snap-on tools online. Nobody else had this socket and its the only one that is made for that caliper.

These are mostly metric now. Sorry the sizes are not listed in the shop manual. Some are TORX head as well. (star shaped). Take a close look to see what you have. Sears will let you return any unused tools.

it takes a 9mm hex head for the front!! just to be safe! call an auto parts store to find out if it is allen or torx bit.

You have mostly metric fastners on all vehicles, since 1980
and some Torx fastners, since around 1995-2000

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.

3/8 allen key or T45 or T50 torx bit. The allen key is the correct tool but the torx bit will work in a pinch.

if its a hex may be 7MM. does it look like a star? its a TORX. you will need a set, pretty cheap at the parts store.

You need a 7mm socket, which are available at auto parts stores.

You'll need a T-55 torx bit to remove the rear caliper pins/bolts. You can try using an insert style bit...one that removes from the socket or perhaps purchase a replacement bit (one that would be used in a cordless drill/driver.) The one I used had a 5/16" hex shank. Like you said, there is very little clearance between the head and the leaf springs, which won't allow room for a breaker bar and torx bit. So using a 5/16" wrench, ( I'd recommend a 6 point box wrench to prevent slipping or rounding off.) I was able to loosen the bolt. Or plan B is to remove the caliper mounting bracket which is held on by two 21 or 22 mm hex head bolts. Which would have to be removed to remove the brake rotor.

I do brakes almost daily on all makes of cars.. Try a 3/8 Allen socket..which are what most Gm brake calipers are
