Mitsubishi Montero (1991+). Manual — part 48

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.

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.
