Diagnosis

1. Review service history to determine if front brake lining wear has been accelerated, typically 3 to 4 times as often as the rear brake linings.

2. If the vehicle is a 2500 series, 8800 GVW, and is operated continuously near the Gross Vehicle Weight Ratings, have the vehicle weighed to determine if the loaded condition is at 75% or greater of the gross vehicle weight rating.

3. 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.

4. If the front brake pads are evenly worn with the rear brake linings indicating light wear, perform the following Repair Procedure.
