NHTSA Campaign 77V055000

SERVICE BRAKES, HYDRAULIC:POWER ASSIST

Issued by MERCEDES-BENZ USA, INC. · Reported Apr 19, 1977 · 449 vehicles affected

What's wrong

AN AIR LEAK COULD DEVELOP THROUGH THE PISTON SHAFT SEAL RING WHICH SEALS THE INSIDE OF THE BRAKE BOOSTER FROM THE ATMOSPHERE. THIS COULD RESULT IN A REDUCTION IN BRAKE BOOSTER ASSIST, NECESSITATING INCREASED BRAKE PEDAL PRESSURE.

Remedy

DEALER WILL REPLACE THE DEFECTIVE SEAL WITH AN IMPROVED VERSION AT NO CHARGE TO OWNER.
