1997 CRV Brake springing

I just bought a 97 CRV with 100k miles on it. On the way home, on 3 occasions when braking and turning at low speeds, the car vibrated a bit, it felt like a spring popped and made a sound of a spring popping. It happened intermittently and braked just fine all the other times. Does anyone have any idea whay this might be? The car has had the right front axle replaced and the CV boot replaced recently and in December had a complete flush and inspection. Help!
