Consequence & remedy
Consequence: THE COMBINATION OF THE FOLLOWING FACTORS MAY COLLECTIVELY RESULT IN AN UNREASONABLE RISK TO MOTOR VEHICLE SAFETY: POTENTIAL FIRE AT A WHEEL END, HIGH INCIDENT RATES OF STUCK CALIPERS, AND EVACUATION AND CONTAINMENT CONCERNS RELATING TO MULTIPLE PASSENGERS.

VEHICLE DESCRIPTION: STRIPPED CHASSIS AND COMMERCIAL BUSES AND SCHOOL BUSES EQUIPPED WITH HYDRAULIC BRAKES AND AUTOMATIC TRANSMISSIONS. THE MISALIGNMENT OF THE BRAKE PEDAL CAN CAUSE DELAYED BRAKE LIGHT ACTIVATION DURING LIGHT BRAKING APPLICATIONS.
Consequence & remedy

Remedy: DEALERS WILL INSTALL A NEW BRAKE PEDAL. OWNER NOTIFICATION BEGAN FEBRUARY 19, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT INTERNATIONAL AT 1-800-448-7825.
VEHICLE DESCRIPTION: TRUCKS EQUIPPED WITH ALLISON 1000 OR 2400 SERIES TRANSMISSIONS. THESE TRANSMISSIONS CAN EXPERIENCE PARK PAWL TO REAR COVER INTERFERENCE DUE TO AN OUT OF FLATNESS CONDITION.
Consequence & remedy
