Caliper replacement questions

[series1gtv]

Hey guys, I've got the calipers off the car but now I've got a problem with getting my calipers seperate from the carriers to put on the new ones. It appears to be a 7MM Allen????!!! Which as far as I can tell may or may not exsist. Where can I find the tool that will allow me to do this?
Thanks
Jeff

7mm is correct. Any allen / hex socket will work.

Use penetrating spray (Kroil, PB Blaster, etc--NOT WD40) first. Use a paper towel wrapped around the extender tube to prevent overspray if you plan on re-using the rotor.

I find it easier to remove those 7mm bolts first and then remove the caliper hanger. I actually use a normal 7mm allen key. It is not long enough to turn by hand, but I tap it with a rubber mallet and it usually spins loose right away. Back those all the way out, remove the calipers. Then remove the caliper hangers if you need to remove the rotor. If you are only replacing the brake pads there is no need to remove the caliper hangers.

I use red loctite to make sure the caliper hangers are secured back to the car.

Pep boys sells the 7mm for $3.99
As Mohaughn said, put the carrier and caliper back and take off the caliper first. It's easier.
