P549RR1

ok guys need some help & diagrams

I just took the car up on the lift and replaced 4 rotors and pads and my Master Cylinder failed, oh well crap like this happens. Only problem is finding it without taking the car apart since it's at the bottom of the engine bay, I think.

Need help with:
1. Diagram of the actual part 130.33129.
2. Easiest way to replace it
3. Download Online schematics welcomed if any aka ETKA etc that doesn't have a virus.

Update: I got the diagram so just to keep Audi Fans informed.

how did the master fail??? it's never happened to me of all the car I've worked on. you just need to be carful you don't get fluid all over when you press the brake cyliders back in when replacing the pads....

I'm sure you know that not every part fails at the same time but what I think happened was that air got into the hose after I had a caliper fail on it. I re-built one rear caliper and I actually just flushed out the master cylinder for cleaning and it was working fine. Either dirt or air not sure but I'm glad I didn't buy the part and it was working after a little cleaning. Next is the VAG code 00139-225 @ 122555-033 (O2 Sensor & Low Pressure Fuel)

Hello i am havin the same issue after a bad caliper, how did you clean the master cylinder??

thank for the help

I flushed all the dirty liquid thru all the calipers and replace it with a different color brake fluid. Once I saw the new color coming from each caliper, I pressurized the system and all was good.
