Caliper line wrench size

[Ruthven13]

I am upgrading my brakes and was wondering what size line wrench I need for the calipers. It's my first foreign truck and am in the process of adding more metric tools to my collection. And once I get my computer back you will probably hear a dealership rant from me. Too difficult to rant appropriately from my phone Just deals with attitude and not being able to connect to my truck's computer. Thanks for any help!

I just did my front calipers yesterday and it was 10mm. Make sure you use lots of penetrating oil leading up to the job, the little threaded collars on the brake lines may not want to rotate. If that's the case you'll have to turn the whole caliper around and around and around like I did! Luckily I noticed it wasn't turning before damaging the line.

I ended up just getting a set of metric caliper wrenches from Advance Auto, came with 6 sizes.

For those who may not know, you should use a flare nut wrench for brake lines--NOT a standard open end wrench.

I think its either 10mm or 5/16

10mm flare nut wrench.

I got one at Home Depot for about 3.00.

Thanks guys! That is the last thing I need, other than motivation. Hopefully the weather and my back will cooperate this weekend. Brakes are not quite at that point yet but I like to leave room for procrastination...

The flare part is key, keep them from rounding off!
