Yeah, I was just hoping to install matching brakes both front and rear. I have a 2 full Shimano 600 groups in the parts bin and both have brakes with recessed nuts. I may just have to use brakes that don't match the rest of the group. Not a big deal but it sure would have been nice (and less expensive) to use matching brakes.
