I see....long reach (drop) caliber brakes are what you need...Also check the wheel is fully seated in the drop out, I have remounted the wheel a little "out" and had brake rubbing issues until I looked again at how I had seated the wheel.

Pretty easy and inexpensive. They will also work a bit better than older brakes....
Possibly something like this:

700c wheels and tires are also referred to as 27.5 inchers... so they should be bigger than the 27 inchers you mention.
Short drop Shimano Golden Arrow (1984) on Raleigh Road Ace frame (1986) with Mavic M40 rims (700C) and 23mm tires.
Long drop/ reach Shimano Ultegra (2014) on 2014 carbon frame. Also runs 700C rims but 28mm tire.
