Rattling wheel sound

If the rattle stops when you hold light pressure on the brake pedal, suspect a loose brake pad. An anti-rattle clip could be broken or rusted off. That is not serious but it can be irritating.

Anti-sway bar links can break and rattle. There's plenty of other possibilities. If the noise started right after the brake work was done that mechanic should be given the chance to check his work. If the noise started two months later it is likely related to something else. Have the steering and suspension systems inspected at a tire and alignment shop. They are real good at identifying the causes of noises.
