I have tried everything from 6mm to 10mm to remove the caliper pins on my front brakes. None of them fit. I have no idea what size I should try. My local auto parts dealer said they think it might be 11mm but they are not sure. I can only order that online. I don't mind ordering it but I just don't want to get it and have it be the wrong one. Anybody have any ideas what the exact one might be?

 

What year is your XC60? Its probably the same as the XC90 which uses a 9mm (some reason many bit kits go from 8 to 10, just like trying to find 16mm and 18mm sockets which Volvo likes to use..

Do you have a Sears or Harbor Freight store near you? There's always Amazon:
For $3 you can afford to be wrong :-)

 

Sorry, I forgot to put that in. It is a 2013. I did try the 9mm and it was to small.

 

are you trying to remove a torx bolt or a hex bolt? just make sure you are using the correct bit type. If you've already tried a 10 mm and its too small as well, I'd go to Amazon and find an 11. Also if you have a Lowes by you, they now carry Craftsman tool so you may be able to find something there.

"no job if worth doing if there's no new tool involved" :-)

 

Sorry the image is so large, it is right from my phone. I tried Lowes they only had up to 10mm. I do see that Homedepot carries it but not in my local area so I can order it. Thanks for the suggestions.

 

Advanced Auto Parts and Napa online also let you buy online and will ship to your local store same day.

 

After following a bunch of advice on the internet (which was wrong) the front brake hex bolt size is 11mm. I picked one up at Home Depot. This job is incredibly easy once you get that hex bolt socket. Good luck.
