1997 AUDI A4 — SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:HOSES, LINES/PIPING, AND FITTINGS

1) FAILURE OF FRONT LEFT (DRIVER SIDE) HYDRAULIC BRAKE HOSE AT CALIPER END AT INBOARD SIDE OF HOSE STRAIN RELIEF. THE DAMAGE LOCATION APPEARS TO BE WHERE HOSE IS SUBJECT TO MAXIMUM STRESS AND FLEXING WHEN FRONT WHEELS TURN. FURTHER INSPECTION REVEALED CONCEALED DAMAGE TO RIGHT (PASSENGER) FRONT BRAKE HOSE AT THE SAME LOCATION. 2) CONSEQUENCE WAS LOSS OF ALL HYDRAULIC BRAKING WHEN HOSE BURST, RESULTING IN MINOR ACCIDENT. DAMAGE TO VEHICLES WAS MINOR BECAUSE OF GOOD FORTUNE TO HAVE FAILURE AT LOW SPEED--NO INJURIES RESULTED. 3) FRONT HYDRAULIC BRAKE HOSES WERE REPLACED WITH NEW OEM HOSES SUPPLIED BY AUDI DEALER. BECAUSE BOTH HOSES EXHIBITED SIMILAR WEAR, OTHER AUDI A4 VEHICLES 10 YEARS OLD AND/OR WITH 100,000+ MILES MAY BE SUBJECT TO SIMILAR FRONT BRAKE HOSE FAILURES. *TR
