the chances are your brake light switch is faulty.the cruise control relies on one side of the switch.
the epc light will come on for this code but will need to be reset through diagnostics port.
hope this helps.
you can also check for codes through the diag port for exact diagnostics.

I dunno if this will work on your BMW, but on my BMW Z3 and M3, it was....

Turn the ignition key to position 2, but do NOT start the car. Wait for about 45 seconds and the brake warning message will be reset.

If it doesn't reset, then the brake sensor was damage. You will need to replace the brake sensor. It sounds like you replace the brake right after you saw the warning, so the brake sensor should be okay.

One method describes just turning the key to position 2 and giving it about 30 seconds and that it will reset on its own. A manual method is described here:
