Consumer Description

WHEN PRESSING THE BRAKES AT ANY SPEED THERE WAS A HISSING SOUND AND THE BRAKES WERE HARD TO PRESS. REGARDLESS OF THE AMOUNT OF PRESSURE I APPLIED TO THE BRAKES THEY DID NOT REACT AND IT TOOK THE VEHICLE LONGER TO SLOW DOWN EVEN AT VERY LOW SPEEDS (5-10 MPH) OR FASTER. THIS CAME ON SUDDENLY AND CAUSED ME TO BRING THE VEHICLE INTO THE SERVICE DEPARTMENT OF THE THE DEALERSHIP WHERE I PURCHASED IT. THE MAZDA TECHNICIAN INSPECTED THE VEHICLES AND COMPLETED A DIAGNOSTICS OF THE VEHICLE AND DISCOVERED THAT THE MASTER CYLINDER AND BRAKE BOOSTER HAVE FAILED AND NEED TO BE REPLACED.
