Anyone know the size of banjo bolt I need for my jaguar xf 2014 rear brake line? It snapped in half and I’m struggling to get any answers! Thanks in advance! If anyone could tell me where to find one I’d also be grateful !

Your best bet is to find a Jaguar EPC (electronic parts catalogue). Whilst some manufacturers seem to use the same sundry items across the range (banjo bolts seem to be common across all Toyota and Lexus products, for example) many do not.

So, you may find that your banjo bolts are different to those of another 2014 XF owner. Hence why it's best to use an EPC as you can check Vs your VIN, or if not there will be an "if you have this spec then it's this, otherwise it's that" choice.

However... If your banjo bolt is snapped you will need to get it out before you can refit the caliper and make the car driveable. So, just retrieve the broken part and measure the thread and dimensions of that (Or get a machine shop/light engineering company to do that for you)

As above, best to get a genuine one if you're at all unsure what you're looking at but, if I had to gamble and buy one unseen, I would say 'almost certainly' M10x1.25 and 20 to 25mm long (you can always shorten it a little). I'm assuming it's a single banjo fitting?
That is the most common thread for brake fittings and it needs to be at least 10mm into the caliper after passing through the banjo itself. Obviously exercise common sense; compare with the old one,
screw in with only fingers first, ensure that it clamps before it bottoms, use new copper washers, don't overtighten, check for leaks after applying sustained brake pressure etc etc.

Thanks both for your comments. I ended up phoning Jaguar and they told me I needed to by the whole brake hose, so searched around and ended up finding a scrap dealer who took the old banjo bolt off and gave me that with some new copper washers for free!

On most cars they are fine thread so M10x1.0

M10x1.25 is Metric Fine
M10x1.0 is Metric Extra Fine, most often found on motorbikes and some Jap stuff

However as he said, most are M10 x 1.0, call it what you like fine/extra fine/super fine, they are still mostly M10 x 1.0.
