NHTSA Campaign 84V032000

SERVICE BRAKES, AIR:SUPPLY:HOSES, LINES/PIPING, AND FITTINGS

Issued by MACK TRUCKS, INCORPORATED · Reported Mar 22, 1984 · 1,163 vehicles affected

What's wrong

FRONT AXLE AIR BRAKE LINES ARE ROUTED TOO CLOSE TO THE ENGINE EXHAUST MANIFOLD. THIS CAN PERMIT BRAKE LINES TO MELT AND RUPTURE, CAUSING A REDUCTION IN AIR PRESSURE TO BRAKE CHAMBERS UPON BRAKE APPLICATION.

Remedy

FRONT AXLE AIR BRAKE LINES WILL BE REPLACED, EMPLOYING NEW ROUTING AND HEAT RESISTANCE IMPROVEMENTS.
