2000 Audi A4 SERVICE BRAKES, HYDRAULIC

THE VEHICLE EXPERIENCED A BRAKE FLUID LEAK. *JB

IN WET WEATHER, 1 - 2 SECOND DELAY FROM BRAKE PEDAL APPLICATION TO BRAKES DEPLOYING. DEALER CONTENDS THAT BRAKES ARE OPERATING WITHIN SPECIFICATION. *AK

I HAVE BEEN HAVING SIGNIFICANT PROBLEMS WITH BRAKING DURING/AFTER ANY TYPE OF RAIN. I HAVE DISCUSSED THIS PROBLEM WITH MANY DEALERSHIPS AND THEY HAVE DENIED EVER HEARING A PROBLEM EXISTS. AS COMMON SENSE INDICATES, DURING ANY TYPE OF RAIN BRAKING POWER WILL BE DECREASED. HOWEVER, THE BRAKING LOSS IN THIS CAR IS BEYOND ACCEPTABLE LIMITS. PLEASE LOOK INTO THE PROBLEM ACCORDINGLY.*AK

WHILE TRAVELING IN SNOWY CONDITIONS, AND WHEN DEPRESSING BRAKE PEDAL VEHICLE WENT INTO EXTENDED STOPPING DISTANCE. PLEASE PROVIDE FURTHER INFORMATION.*AK

IN RAIN THERE IS A 2 SECOND DELAY AFTER THE BRAKES ARE APPLIED BEFORE THEY BITE. THIS ONLY HAPPENS IN WET CONDITIONS.*AK

VEHICLE EXPERIENCES DEGRADED BRAKE PERFORMANCE IN WET CONDITIONS. DEALER IS SCHEDULED TO INSPECT VEHICLE. *AK

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

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

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. THE CAR SPUN AND WENT TO AN EXIT LANE AND HIT ANOTHER CAR FORCING IT OFF THE ROAD BEFORE COMING TO A COMPLETE STOP. THE CAR IS NOW UNDRIVEABLE. *AK

BRAKING IS POOR IN WET CONDITIONS. TAKES 1 TO 2 SECONDS BEFORE BRAKES RESPOND. *AK

BRAKES DO NOT PERFORM WELL IN WET WEATHER. *AK

INITIAL BRAKING IN WET CONDITIONS IS POOR. AFTER APPROXIMATELY 30 SECONDS OF NON-USE OF BRAKES IN HEAVY MIST OR SPRAY, OR ANY PRECIPITATION, THERE IS LITTLE TO NO BRAKING ACTION FOR APPROXIMATELY 1 SECOND AFTER THE PEDAL HAS BEEN DEPRESSED. NO BRAKE PEDAL "PULSING" (ASSOCIATED WITH ABS ACTIVATION) IS NOTICED. CRUISE CONTROL WAS NOT ACTIVE EACH TIME THE PROBLEM WAS NOTICED. THE PROBLEM IS MORE NOTICEABLE AT HIGHWAY SPEED. BRAKES ARE OTHERWISE EXCELLENT. *AK

WHILE DRIVING IN HEAVY RAIN, THE ROTORS FELT AS THOUGH THEY HAD A SHEEN ON THEM THAT CAUSED THE BRAKES NOT TO FUNCTION IMMEDIATELY. ALMOST AS IF THE VEHICLE WAS SLIDING ON ICE. THIS OCCURED 4 TIMES IN THE COARSE OF A 150 MILE TRIP FROM PHILADELPHIA TO NEW YORK CITY. *AK

WET-BRAKING PROBLEM. DURING HEAVY RAIN, WATER DROPLETS ACCUMULATE ON DISKS AND CAUSE A 2 SECOND DELAY IN BRAKING ACTION!!!. *AK

BRAKE ACTION IS DELAYED WHEN THERE IS RAIN. NLM

WHEN DRIVING IN RAINY CONDITIONS BRAKESFAILED TO ENGAGE FOR SEVERAL SECONDS AFTER DEPRESSING PEDAL, CAUSING A VERY DANGEROUS DELAY. *AK

WHEN BRAKES ARE WET AFTER DRIVING A LONG DISTANCE AND ARE NOT USED - THEY FADE THE FIRST TIME YOU USE THE BRAKE PEDAL.

BRAKE FAILURE OCCURRED UNDER WET CONDITIONS. BRAKES WERE APPLIED AT 30 MPH, BUT DID NOT ENGAGE FOR A FEW SECONDS (3). BRAKES "CHATTERED" BEFORE CAR EVENTUALLY STOPPED, AND LUCKILY THERE WAS CLEAR TRAFFIC AHEAD OF ME. *AK
