DURING HIGHWAY DRIVING IN THE RAIN, WATER DEVELOPS ON THE BRAKE PADS/ROTORS, CAUSING THE DELAY IN BRAKING. WATER BUILDUP SEEMS TO OCCUR AFTER ABOUT 2 MINUTES OF DRIVING IN MODERATE OR HEAVY RAIN. BRAKING DELAY IS ABOUT 1.5 SECONDS. WHEN BRAKES GRAB, THEY SOMETIMES GRAP UNEVENLY, PULLING THE CAR TO ONE SIDE OR THE OTHER, UNTIL ALL 4 CORNERS HAVE CLEARED THE EXCESS WATER...THEN NORMAL BRAKING RESPONSE RESUMES. I HAVE WORKED AS A PROFESSIONAL DRIVER, DRIVING DIFFERENT VEHICLES OVER LONG DISTANCES...THIS IS NOT NORMAL!!! I KNOW FROM ON-LINE FORUMS THAT AUDI HAS NOT DIAGNOSED THE PROBLEM, AND AS SUCH, DOES NOT HAVE A FIX OUT YET. I TRIED REPLACING BRAKE PADS, THIS DID NOT HELP.
BRAKES TAKE 2-3 SECONDS TO RESPOND ON FIRST USE WHEN DRIVING IN VERY WET CONDITIONS. HAS HAPPENED ABOUT 12 TIMES IN THE LAST YEAR. DEALER SERVICE DEPARTMENT OFFERED NO FIX.*AK
IN WET WEATHER, 1 - 2 SECOND DELAY FROM BRAKE PEDAL APPLICATION TO BRAKES DEPLOYING. DEALER CONTENDS THAT BRAKES ARE OPERATING WITHIN SPECIFICATION. *AK
UNDER WET CONDITIONS, BRAKING IS DELAYED. ESPECIALLY NOTICEABLE WHEN TRAVELING AT HIGHWAY SPEEDS, BRAKING SUDDENLY, AND FOR A MOMENT, BRAKES SEEM TO NOT WORK. *AK
BRAKING IS POOR IN WET CONDITIONS. TAKES 1 TO 2 SECONDS BEFORE BRAKES RESPOND. *AK

I WAS DRIVING AT NIGHT ON THE ROAD ENTERING A HIGHWAY AT ABOUT 35 MPH WHEN I SPOTTED SOMETHING ON THE ROAD. BEING THAT MY VEHICLE IS AWD AND EQUIPPED WITH ABS I BROKE AND SWERVED. I FELT NO RESPONSE FORM THE BRAKES AND BY THAT TIME (2-4 SECONDS) MY CAR HAD LOST CONTROL AND STARTED TO SPIN.

2001 AUDI A4 BEGAN TO SMOKE. DROVE 5 MINUTES TO A FRIEND'S HOUSE AND PARKED IN DRIVEWAY, CONSUMER WENT INSIDE OF HOUSE, AND CAR WAS SITTING FOR 20 MINUTES. THEN, SOMEONE KNOCKED, AND TOLD CONSUMER THAT CAR WAS SITTING IN THE MIDDLE OF TRAFFIC. CAR DISENGAGED ON ITS OWN, AND ALMOST RAN OVER TWO CHILDREN. TOOK TO DEALER, AND THEY SAID BACK BRAKE PADS, AND ROTORS WERE BURNED TO A CRISP. NO CONCLUSION TO WHY THIS HAPPENED OR WHY CAR ROLLED INTO TRAFFIC ON ITS OWN.*AK ALSO, THE BRAKE PEDAL WENT TO THE FLOOR WHEN THE CONSUMER APPLIED THE BRAKES. THE CONSUMER'S INVESTIGATION SHOWED THAT THERE WERE NUMEROUS REPORTS ABOUT SPONGY BRAKES REGARDING THIS VEHICLE. THE CONSUMER FEELS UNSAFE DRIVING THIS VEHICKE BUT THE DEALER AND THE MANUFACTURER COULD NOT FIND SOLUTION TO THE PROBLEM. *YH
WHEN BRAKES ARE WET AFTER DRIVING A LONG DISTANCE AND ARE NOT USED - THEY FADE THE FIRST TIME YOU USE THE BRAKE PEDAL.
