Should be very obvious, right next to the cross over pipe on the side without the hose.
But it might be yours have been modified or replaced with something else. Can you post a photo?

Hello,

If they have been broken off bless you my son. Getting them out is often a slow task but almost always possible and involves heat and smoke.

Get that area of the caliper hot not just warm but hot with a torch and melt a candle into the threads. Using an easyout or simply jamming in a minus screwdriver into it
will likely turn it out.

Here's a picture of a broken bleed screw (near my index finger) on the caliper. I wish I had John's advice in removing it before I made my failed attempt! I didn't try heat because I was fearful of cracking the casting. I tried soaking in WD40 and using progressively larger EZ-outs until my drill drifted and I damaged the threads. I ended up bringing it to a professional who saved the day by drilling it out completely, tapped the larger hole, fabricated a custom sleeve to screw in and micro-welded it in place. He saved the day for me but at a cost of $250!

Listers,

I do not know why the heat/candle issue lets us extract rusted bit but my humble experience has been
positive.
