You squeezed the brake? You squeezed the wheel? First, is the brake centered around the rim? Make sure the brake caliper (is it a caliper or canti or linear pull brake?) is firmly mounted to the frame and that you can't wiggle it back and forth by hand. Most modern brakes have tiny screws or allen bolts that adjust the centering. If you want to try it, turn one screw 1/4 turn and see what happens. As a rough guideline on truing, your wheel should wobble no more that 1 mm when it's new or just been trued, unless the rim is old and well-used. If it's wobbling by 3-4 mm or more or hitting a well-adjusted, centered brake, probably time to true. However, sometimes brakes can be adjusted so closely that really small rim deviations lead to rubbing, so you have to be sensible about both brake adjustment and rim trueness.
