Recall 79V-054: 1979 Ford B700, 1979 Ford B800 and 2 more

The problem

The air brake lines may be routed too close to the exhaust muffler. Because the air brake lines are made of nylon material, heat from the exhaust muffler can weaken the brake line tubes, possibly causing them to rupture. Tube rupture could result in loss of air in the secondary air brake system.

The fix

New nylon air brake tubes will be installed and rerouted without charge to owner.
