Hi everyone,

I'm going to do a brake fluid flush for the first time. Reading the manual now it only says to take the car to an authorized Audi dealer and it doesn't even provide minimum specs for braking fluid.
Also what's the brake fluid system capacity? How many litres of brake fluid should I get replace all the old fluid?

Does anyone know what Audi uses? (stock brakes)

Also I'm going to pressure flush the system (1 person method) and I was told that the pressure used to flush brake fluids may vary depending on each vehicle.
Usually, it's recommended to use a pressure of between 1 and 1.5 bar. Is that pressure safe for the S5?

Thank you in advance
