2010 mazda tribute brake replacement.
 

Haveing issues takeing the bottom bolts out of the brake pad houseing. The top ones came out fine but the bottom ones keep sliping with the alenwrench 1/4 that im useing is the only size that fits. Its thier something else out their that would work

Pretty sure I use a 7mm on mine, 1/4" is only 6.35mm

I've got a 2005 Tribute and a 2008 Tribute. The 2005 takes a 7mm and the 2008 takes a 9mm. I'm guessing a 2010 would take the 9mm.
