2010 AUDI TT-RS BRAKES FAIL
 

HI THERE ! I GOT MYSELF A TT-RS , AND I HAVE IT NOW FOR 2 MOUNTHS. UNDER HARD DRIVING ON PUBLIC ROADS I HAVE A PROBLEM OF BRAKES THAT FAIL ! IT IS A MANUAL AND WHEN I PUSH THE BREAK PEDDLE IT'S LIKE PUSHING THE CLUTCH PEDDEL. NO BRAKES FOR A LONG TIME ??? WHEN THE CAR IS COOLD DOWN EWERYTING WITH THE BRAKES IS OK. I WANT TO KNOW WHY THIS HAPPENS ? IT IS AN "RS" SO I DO USE THE POWER , BUT IT IS UNSAFE !!!! SHULD AUDI TRY DIFFRENT BREAK FLUAD ?

No such car sold in North America
 

First model year for the TT-RS sold in North America was 2012. Perhaps you have a TT-S or a TT roadster S?

Audi USA did have a TT-RS prototype in the USA in 2010 but that was destroyed at then end of 2010 as required by federal law. I was lucky enough to drive it at that year's TT West event.

In any event, the TT barkes are solid, so the issue is with your car. If the equipment is still OEM, your brake fluid probably needs changed. If it is not OEM, you probably have crap aftermarket pads. There are a lot of good aftermarket pads out there but also some junk.

Sounds like you are overheating the brakes or more specifically your fluid is not operating effectively because the temperature is too hot and causing the fluid to get too hot and thus lacks the ability to harden the pedal which gives you the braking effort. This is common for any car driven hard & fast.

Quick fix is to upgrade the original Audi brake fluid for something with higher boiling point. Castrol SRF is popular and well stock round the globe. That will help in the first place to ensure the brake pedal at least stays hard long to help you.

IF you are boiling the Audi fluid then chances are that your pads are also operating beyond their temperature window. You will need to find a performance tuning specialist local to you to discuss fitting improved brake pads however with a performance oriented brake pads you may introduce brake noise and increased brake dust.

Where are you located in the world?

Hope above help.

HI ! HERE IN SOUTH AFRICA WE HAD THE TT-RS OUT ON PRODUCTION AT THE END OF 2009. 250kw MOTOR AND 450nm TORQUE. BUT IT WAS ONLY AVALABLE IN MANUAL AND ONLY FROM 2012 WE HAD THE OPTION ON A DSG BOX. NOW MY 2010 TT-RS (250kw) WITH THE BRAKE PROBLEM... I SEND IT IN TO AUDI CENTRE FOR A REPAIR (MY CAR HAVE A 5 YEAR 100 000km FREEWAY PLAN) , IT TOOK AUDI S.A 5 DAYS TO TELL ME THAT THEY CAN'T SOLVE THE PROBLEM , THE OTHER TT-RS THEY TESTED IS DOING THE SAME. NOW... I THINK I AM GOING TO RIGHT A LETTER AND GO THE LEGAL ROUTE TO TELL AUDI S.A THAT IF ANYTHING HAPPENS TO ME AND MY FAMILY I WILL HELD THE RESPONSABLE . THIS IS A MAJOR PROBLEM !!!

IN SOUTH AFRICA WE HAVE THE 250kw TT-RS SINCE 2009 . OUR DSG ARRIVED IN 2012. WE HAVE BOUTH MODELS ON SALE IN S.A.

HI WILLIAM ! THANK YOU FOR RESPONDING . I FEEL THAT AUDI MADE THIS TT-RS AS A HI PREFORMANCE CAR AND THE BRAKING SYSTEM IS USLESS. IF I WHERE THEM I WILL DO A TOTAL RECALL AND REPLACE THE BRAKE FLUID FOR HIGER TEMP. MY BRAKE FLUID WAS REPLACED BY AUDI AGENT NOW , BUT STILL THE SAME. I FEEL THE ONLY WAY AUDI S.A WILL KNOW THE PROBLEM IS WHEN SOMEONE HAS A FAITAL CRASH .

TT-RS 250kw WAS AVALABLE SINCE END 2009 IN SOUTH AFRICA. I KNOW FOR A FACT I HAVE AN ORIGANAL TT-RS I WILL POST A PIC.

Sorry, unless stated, we Yanks assume posters are in the USA
 

I have seen no reports on this or other USA boards regarding brake fade on the RS. There have been many complaints about brake squeal here.

Did you replace for another Audi fluid or improved thus Castrol SEF?.

HI! THE FAULT ON THE BRAKES IS IN S.A ALL AUDI'S USE DOT 4 BRAKE FLUAD. WHERE A DOT 6 WILL BE THE STUFF WITH A HIGHER BOILING POINT. BUT AUDI S.A DON'T HAVE ALL THE NUMBERS OF UNHAPPY CUSTOMERS TO CHANGE TO DOT 6.
