Mike, forget about anyone who does not know the 928 working on this - contact Jim Doerr (
jim@928classics.com ) he is in Richmond and see who he recommends.
From the owners manual.
BRAKE PRESS warning light flashes if one
of the circuits in the brake system should fail.
Because of the way the two pressure switches work, you can't easily bypass them - a flashing brake light indicates brake circuit pressure failure or low fluid level - There are two circuits, up to '83 front left and rear right, front right and rear left; '84 on circuits are divided by axle, front and rear.. If one fails the other continues to provide reduced braking, and the light flashes continuously.
