SERVICE BRAKES
Description:IN MY DRIVEWAY ON DRY PAVEMENT AT SLOW SPEEDS WHEN PRESSING THE BRAKE PEDAL THE VEHICLE DOES NOT STOP SATISFACTORY. THE BRAKE PEDAL WAS THEN PRESSED UNTIL IT WAS VERY HARD THE VEHICLE CONTINUED TO MOVE BUT SLOWLY BEGAN TO STOP. WHEN PRESSING THE BRAKE PEDAL TO THE MAXIMUM AND A FIRM PEDAL A NOISE COULD BE HEARD FROM UNDER THE HOOD. THE NOISE SOUNDED LIKE A MOAN, SIMILAR TO THE BRAKE ANTI SKID SYSTEM BEING ACTIVATED. I WAS ABLE TO SIMULATE THIS BRAKING PROBLEM MULTIPLE TIMES WHILE BACKING UP AND MOVING FORWARD AT SLOW SPEEDS. CYCLING THE IGNITION ON AND OFF DID NOT CORRECT THE PROBLEM.
