William,
The brake problems will not show up as an error on the ECU (checked with the fuse in the fuel pump slot). It sounds like you the pressure accumulator (aka - "bomb") is failing. See:

Cheers!

This audi is 15 years old, now if I applied the brakes, the dash board will beep four times, along with the red light in the center ( with exclamation mark ) blinking 4 times, then 4 more times without the beeps.

Any ideas ? On board diagnostic computer reports code 4 4 4 4, which indicates everything is fine.
Thanks guys.

Bill.
