Does anyone know what kind of calipers these are?

I just bought this T and the brakes squeak. I want to replace the pads but I don't know what kind of calipers I have.

I cannot be any help on the identification, but how do you bleed the caliper? All the area above the bleeder screw will be air, unless you rotate the caliper to put the bleeder at the top, right?

What he said, and yes, you have to rotate them to bleed them. I take mine completely out and use a vacuum bleeder that runs off the air compressor.
