Banjo Bolt Help

[KingChuck24]

I have been trying to install the banjo bolt on all of the brakes, I have cleaned off most of the powder coat and they still don't go in. Does anyone know what size of tap they need, we tried tapping out with, what it think is, the wrong size and may have messed up the threads a bit:

The threads look damaged. I can’t tell ya the size, but if you have a tap and die set, there should be a thread gage in the there. Use that to find the thread pitch, then match up the size.

note:
You’ll need to remove the powder coat from the mating surface, so the brass washer can seal properly too.

Edit
when I’m in the garage later today I can check it if I have an extra banjo bolt laying around.

M12x1.5 iirc

M12x1.5 iirc

I don’t think this is correct, the m12 seems way to big

Time for a new tool?

Got one of these not to long ago. I use it way more than I thought I would

That looks very useful, unfortunately out of stock. I think I will just go to my hardware store with the banjo bolt and check the size and buy the tap for that thread.

Just remember that the threads aren't determined by just bolt diameter but also thread pitch and in more unusual cases, thread profile. It won't surprise me if the banjo bolt isn't a standard course thread and is instead a fine thread pitch. M10 and M12 actually have at least thread pitches possible.

You're right; it's actually M10x1.5

Just checked, the rear is M10 x 1.0 and the front is M10x 1.5. Yes they are different and yes I ruined one of the banjo bolts thinking they are the same...

Right, I didn't think to check the Solstice/Sky calipers.
