2000 NISSAN PATHFINDER Unknown Or Other Problems

I HEARD A RUBBING SOUND AND THE PASSENGER SIDE FRONT BRAKE WAS ACTING UNUSUAL SO I TOOK MY TRUCK TO MY MECHANIC ASSUMING IT NEEDED BRAKES.

I FEEL THAT THIS IS A SAFETY ISSUE THAT COULD CAUSE A SERIOUS OR FATAL ACCIDENT IF I WERE TO HIT A POTHOLE AT ON A HIGHWAY AT A HIGH RATE OF SPEED. AFTER INVESTIGATING THE INCIDENT FURTHER, I HAVE COME TO FIND OUT THAT THIS...
