Front Disc Brakes

Lining Inspection Points:

Inspect the brake linings every 6,000 miles and any time the wheels are removed (tire rotation, etc.). Check both ends of the outer lining by looking in at each end of the caliper. These are the points where the highest rate of wear normally occurs. At the same time, check the thickness of the inner lining to make sure it has not worn prematurely. Some inboard shoe and linings have a thermal layer against the shoe, integrally molded with the lining. This extra layer should not be confused with uneven inboard-outboard lining wear. Look down through the inspection hole in the top of the caliper to view the inner lining. Replace disc brake shoe and lining assemblies whenever the thickness of any lining is worn to within 0.76 mm (0.030 in) of the shoe. Replace riveted shoe and lining assemblies when the lining is worn to within 0.76 mm (0.030 in) of any rivet head. Always replace disc brake shoe and lining assemblies as a complete axle set.





Check the flatness of the brake pads. Place the inboard and outboard lining surfaces together and check for a gap between the lining surfaces. This gap should not exceed 0.13 mm (0.005 in) at the middle of the lining surfaces. This applies to new or used brake The factory installed and equivalent disc brake pads have a wear indicator that contacts the rotor to make noise when the linings wear to the point of needing replacement. A loud scraping/squealing sound can be heard when this occurs. It should be noted that an occasional squealing noise may be considered normal and is not a positive indicator that service is required. It is recommended that the condition of the brakes are inspected as noted in the maintenance schedule.
