Disc Pads

Original Equipment Manufacturer (OEM) specifications designate replacement at different thicknesses. It is required that friction material be matched in axle sets for consistent braking characteristics. Monroe® recommends using an OE-approved brake line locking device.

Condition Code Procedure
Contaminated, for example, fluid that leaked from caliper, wheel cylinder, or axle seal A Require replacement
Identify and repair cause of contamination prior to replacing friction material.
Cracked through B Require replacement
Flaking or chunking B Require replacement
Glazed (shiny) No service suggested or required
Grooves or ridges No service suggested or required
When reconditioning or replacing drums or rotors, replacement of friction material may be suggested depending on the severity of the grooves or ridges.
Permanently attached hardware bent A Require replacement
Permanently attached hardware broken A Require replacement
Permanently attached hardware loose A Require replacement
Permanently attached hardware missing C Require replacement
Permanently attached hardware seized A Require repair or replacement
Rivets loose B Require replacement
Separating rom backing B Require replacement
Shoe table or web bent B Require replacement
Shoe table or web cracked A Require replacement
Shoe table or web worn, affecting performance A Require replacement
Surface cracking No service suggested or required. Further inspection may be necessary to determine cause
Tapered wear B Suggest replacement
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.
Thickness of one pad is greater than opposite pad in the same caliper (uneven wear) Replacement of friction material not suggested or required. Further inspection required. See Calipers and Caliper Hardware
Uneven pad thickness is normal on some vehicles. Refer to specific vehicle applications.
Wear indicator device (electronic) contacts rotor B Require replacement of appropriate parts
The pad-wear indicator light may come on due to other electrical problems.
Wear indicator device (mechanical ) broken Further inspection required
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.
Wear indicator device (mechanical ) broken Further inspection required
The need for friction material replacement is determined based upon the conditions stated in this section. Periodic inspection is suggested.
Wear indicator device (mechanical) bent Further inspection required
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.
Wear indicator device (mechanical) bent Further inspection required
The need for friction material replacement is determined based upon the conditions stated in this section. Periodic inspection is suggested.
Wear indicator device (mechanical) contacts rotor Further inspection required
The need for friction material replacement is determined based upon the conditions stated in this section. Periodic inspection is suggested.
Wear indicator device (mechanical) contacts rotor Further inspection required
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.
Worn close to minimum specifications 1 Suggest replacement
When the part appears to be close to the end of its useful life, replacement may be suggested.
Worn to, or below minimum specifications B Require replacement
