Disclaimer - I've never fixd this on a rocco, but it sounds like a problem I've
had on other cars.

Check the earth connection for your right-hand rear light cluster - it's
probably corroded. This is the same problem that makes For Escort (do you get
those?) brake lights flash with the indicators, and makes my Citroen warn me of
a defective rear light when I indicate.

When the extra current is flowing through the brake light circuit, the "earth"
point voltage rises - because you have grown a new resistor there. This means
that the flasher circuit doesn't have a proper earth - so it fails.
