The problem
ON CERTAIN MEDIUM DUTY TRUCKS, THE BRAKE VACUUM HOSE MAY HAVE BEEN MANUFACTURED WITH INSUFFICIENT WALL THICKNESS ALLOWING THE HOSE TO COLLAPSE DURING NORMAL VEHICLE OPERATION.
Risk
CONTINUED OPERATION OF THIS VEHICLE IN THIS CONDITION COULD (1) WITH RESPECT TO THE FE83D FE84D, AND FG84D MODELS, RESTRICT PROPER OPERATION OF THE BRAKE POWER-ASSIST AND COMPROMISE BRAKING PERFORMANCE; AND (2) WITH RESPECT TO THE FE85D MODEL, RESTRICT PROPER OPERATION OF THE EXHAUST BRAKE SYSTEM. EITHER OCCURRENCE COULD LEAD TO COMPROMISED BRAKING PERFORMANCE AND INCREASED BRAKING DISTANCES, WHICH COULD CAUSE A CRASH WITHOUT WARNING.
What owners should do
DEALERS WILL REPLACE THE BRAKE VACUUM HOSE WITH A HOSE MANUFACTURED WITH WALLS OF PROPER THICKNESS. THE RECALL BEGAN ON AUGUST 20, 2007. OWNERS MAY CONTACT MITSUBISHI FUSO AT 1-856-467-3917.
