SERVICE INFORMATION

Service brake pads with improved semi-metallic material are available for the applied models. These pads have been installed at the factory on some 1987 and most 1988 models. Compared to the former semi-metallic material, this new material has the following advantages:

^ Reduced brake pedal effort when brakes are cold
^ Firmer brake pedal "feel"
^ Reduced brake rotor wear
^ Reduced brake squeal
^ Reduced brake noise after vehicle has been in storage (less affected by rust on rotor surface)

In addition, this new semi-metallic material has much longer pad life than the equivalent asbestos pads.

Service brake pad kits with this new material are available and have new part numbers. They can also be identified by the code stamped in the pad backing plate.

Original pad material (asbestos) NBK NP01 FF
or (semi-metallic) Hitachi HP14 EE

Improved pad material (semi-metallic) Hitachi HP12 FE

The improved pads can be substituted for the original pads and are recommended for all repairs when the brake pads are replaced.






PARTS INFORMATION

Use the following chart to find the correct part numbers for the new brake pad kits with HP12 material. Models that are not listed on this chart (i.e. Z31, certain D21 models), use brake pads from a different vendor. Use the original pads listed in the Parts Microfiche. Original pads on these models are equivalent to HP12 material.
