I'd have to go back and double check on the exact size. It's like a allen head wrench, but in socket form https://www.nopistons.com/forums/pub...IR#>/smile.gif you may be able to use a wrench, but depending on tight yours is, it may bend... sockets are much better.



A lot of auto parts stores sell "brake socket kits" which consist of like 3 or 4 allen/hex sockets - just pick one up thats made for a ford/mazda.. its cheap, under $12.. you can never have too many tools!

Amen, brother! Amen.

ok, that's what I'll do. thanks!

If you are going to do brakes on a regular basis i would buy a hex socket set, no a little hex key will not do the trick. snap on has a decent set and i am sure sears does too, they are nice to have, even the 70's and 80s Jeeps used hex bolts for the calipers.

7mm hex, 18mm socket. took 2 trips to walmart. i'm drunk off mygray goose payment,, however.
