         FRICTION MATERIAL

NOTE:    Original Equipment Manufacturer (OEM) specifications

         designate replacement at different thicknesses.

CAUTION: It is required that friction material be matched in axle

         sets for consistent braking characteristics.

 greater than opposite pad

 in the same caliper

 (uneven wear)  ..........  ..  ....  (4) Replacement of friction

                                        material not suggested or

                                     required. Further inspection

                                           required. See  CALIPERS

                                            and  CALIPER HARDWARE.

                                                        required.

Worn close to minimum

 specifications  .........  1  ........  (7) Suggest replacement.

Worn to, or below minimum

 specifications  .........  B  ............  Require replacement.

(1) - Identify and repair cause of contamination prior to

      replacing friction material.

(2) - When reconditioning or replacing drums or rotors,

      replacement of friction material may be suggested

      depending on the severity of the grooves or ridges.

(3) - Some vehicles use pads that are tapered by design. Refer

      to specific vehicle application. If not normal, require

      replacement of pads and correction of cause.

(4) - Uneven pad thickness is normal on some vehicles. Refer to

      specific vehicle applications.

(5) - The pad wear indicator light may come on due to other

      electrical problems.

(6) - Explain to the customer that the purpose of the wear

      indicator is to alert him or her to check for friction

      wear. Wear indicators may be bent or broken. Therefore,

      the friction material must be measured. The need for

      friction material replacement is determined based upon

      the conditions stated in this section. Periodic inspection

      is suggested.

(7) - When the part appears to be close to the end of its useful

      life, replacement may be suggested.
