If the brakes don't have enough reach, they can be simply swaped them out for longer reach calipers. Of course this would require purchasing new brakes, but if it lets you be more comfy on your bike it would be worth it. I know shimano makes a long reach side pull brake that is often used on touring bikes since they also give more room for wider tires. In fact, if I recall the trek pilots may have been equipped with these since I recall they do accomodate wider tires, but you'll need to check the specs. Which pilot do you have? Looking at them does it look like the brake pads can be adjusted further down?
