In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 12% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.
ACTION REQUIRED
Inspect the 284-9557 Service Brake Separator Plates and 259-6836 Friction Discs for warping or excessive heat discoloration. Refer to the Disassembly and Assembly publications KENR6019 for instructions for removing the wheel group. See attached salvage and replacement guidelines. If separator plate or friction disc replacement is necessary, review operating environment and recommend implementation of PS43037 compression brake retrofit if appropriate. Additional brake failure claims may be rejected if PS43037 is not performed for the appropriate applications.

Rework Procedure
Disc Replacement Guidelines
1. Measure friction disk thickness with a micrometer as shown in the picture. Replace friction disc if it has more than 50% wear indicated by a thickness of 3.45 mm (0.136 in) or less.
2. Measure lining wear on both sides of the disc. The lining wear should be approximately even side-to-side. The lining in one side of the disc should not be less than ? the thickness of the other side. Lining wear that exceeds the groove depth is not permitted on either side at any location.
3. Do not reuse a disc if more than 10% of the friction material has ?flaked? off or if the friction material appears to be very easily chipped when applying light prying pressure.
4. ?Warped?, ?glazed?, and/or ?burnt? discs that exhibit signs of excessive temperature should be replaced in all instances. Do not reuse a plate that is warped. A plate is considered warped if a 0.25 mm (0.010 in) feeler gauge will fit between the plate and a flat surface.
5. Inspect the disc teeth. Do not reuse discs with broken teeth.
