Here are some pictures. The first two are of the location I am hoping to mount the side pull brake. The last image is of the original mounting location for the centre-pull brake.

So even though the support between the seat stays might be strong enough to mount a brake it might not be a great idea. Hmmmm.... I would really prefer to mount a side pull brake. It doesn't have to do with trying to build on a budget or anything. I would just like to have matching brakes front and back and would prefer to use side pull. I think it will just look cleaner to have the brake mounted between the seat stays.

If I use side pull is my only option to put the cable in through the bottom?



Thanks for all the insight.
