THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 05-08-99, DATED JULY 2, 1999, WHICH SHOULD BE REMOVED FROM
YOUR FILES. BRAKE ROTOR P/N 52007715 HAS BEEN ELIMINATED FROM THE PARTS REQUIRED SECTION LEAVING BRAKE ROTOR

SUBJECT:
Accelerated Brake Lining Wear, Front Versus Rear
OVERVIEW:
This bulletin involves replacing the front and rear brake linings and the rear wheel cylinders.
MODELS:
1996 - 1997 (AB) Ram Van/Wagon
NOTE:
THIS BULLETIN APPLIES TO 2500/3500 SERIES VEHICLES EQUIPPED WITH THE HEAVY DUTY 9-1/4 REAR AXLE (SALES CODE
DRG).
SYMPTOM/CONDITION:
Front brake linings wear prematurely when compared to the wear experienced on the rear brake linings. Normally, it is expected that the front brake
linings will require replacement approximately twice before the rear lining assemblies will need replacement. The accelerated wear condition can be
identified by requiring the front brake linings to be replaced three to four times before the rear lining assemblies are replaced.
NOTE:
CORRECT REAR BRAKE ADJUSTMENT IS A MAJOR FACTOR TO IMPROVE FRONT BRAKE LINING LIFE. IF THE VEHICLE IS NOT
FREQUENTLY OPERATED IN A REVERSE DIRECTION WITH AGGRESSIVE AND COMPLETE BRAKE STOPS TO AUTOMATICALLY
ADJUST THE REAR BRAKES, THE VEHICLE MUST HAVE A MANUAL REAR BRAKE ADJUSTMENT PERFORMED EACH 8047
KILOMETERS (5,000 MILES) OF VEHICLE OPERATION. REFER TO THE APPROPRIATE RAM VAN/WAGON SERVICE MANUAL,
GROUP 5, FOR INFORMATION REGARDING REAR BRAKE "ADJUSTMENT WITH ADJUSTING TOOL."
DJAGNOSIS:
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.
Raise the vehicle on a hoist.
3.
Remove all four tire/wheel assemblies and the rear brake drums.
4.
Visually inspect both front and rear brake assemblies for any signs of abnormal wear with any braking component, abuse, or mis-assembly ot
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.
5.
Visually inspect the parking brake mechanism for proper operation and adjustment. Refer to the appropriate Service Manual, Group 5, for
information regarding service of the parking brake system.
6.
It the brake pads are evenly worn with the rear brake linings indicating light wear, perform the Repair Procedure.
