yes more or less. it is a thing about 1/4" diameter that sticks out maybe 3/4" from the caliper with a rubber turban looking thing that covers the end to keep dirt out. there is a fitting for a wrench about 8 mm or 10mm.

when first loostening a bleeder, first spray with wd 40 or pb blaster, then put your wrench on and wiggle it a bit. they often are rusty and they are hollow so they will break off easier than a bolt same size.

good luck
