Whenever I brake and I'm about to come to a full stop, I hear what sounds like a hammer hitting a nail, just ONCE per stop, coming from the front of the car. Also, sometimes the ABS light goes on randomly, stays on for a while and then goes off, even though ABS is not being used. The ABS thing happens once in a while usually after heavy driving, and the "clank" sound happens just about every full stop.

Any car gurus have an idea what's going on?

This is on a 95 Integra...

Thanks
