NUMBER: 05-06-99GROUP: Brakes
DATE: June 25, 1999
SUBJECT:
Accelerated Brake Lining Wear, Front Versus Rear
OVERVIEW:
This bulletin involves replacing the front and rear brake linings.
MODELS:
1994 - 1999 (BR/BE) Ram Truck

SYMPTOM/CONDITION:
Front brake linings wear quicker when compared to the wear experienced on the rear brake linings. Typically, it is expected that the front brake linings will require replacement approximately twice before the rear lining assemblies will need replacement. Replacing the front brake linings more frequently would be considered accelerated front lining wear.
DIAGNOSIS:
1. Review service history to determine if front brake lining wear has been accelerated.
2. Visually inspect both front and rear brake assemblies for any signs of abnormal wear, abuse or mis-assembly of components. Refer to the appropriate Service Manual, Group 5, for information regarding service of braking components if the brake assemblies show signs of abnormal wear, abuse or mis-assembly of components
3. If the front brake pads are evenly worn with the rear brake linings indicating light wear, perform the following Repair Procedure.
