1995 Maxima

With 114,000 miles. Clanking noise coming from what sounds like the passenger side left wheel, but not positive. Noise is in synch with the rotation of the tire. The slower the car is moving, the slower the clanking. When I brake, even slightly, noise disappears. Most noticeable when going slowly. Mechanic looked it over, could not find the source. Had rear brakes replaced because they were needed, noise morphed from grinding sound to clanking at that time. Don't know if it's related issue. Help!
