The problem
BRAKE BOOSTERS HAVE BEEN IMPROPERLY ASSEMBLED WITH THE TWO HALVES OF THE BOOSTER UNIT INSUFFICIENTLY CONNECTED.
Risk
BRAKE BOOSTER HALVES COULD SEPARATE UNDER HEAVY BRAKEAPPLICATION AND BRAKING POWER WOULD SUDDENLY DIMINISH WHICH COULD RESULT IN ANACCIDENT.
What owners should do
REPLACE BRAKE BOOSTERS AS NECESSARY.
