BRAKES 23 DISC INSPECTION : Before assembling the caliper back to the carrier, the disc should be inspected. The disc should be cleaned with dry cloth, oil traces to be wiped out completely. The disc should be free from score marks. If scored, it should be ground and refitted. Following precautions should be taken during grinding:  At no time more than 0.25 mm (0.10”) should be ground per side.  If the total thickness of the disc after grinding is found to be less than 24 mm in case of front disc and 10mm in case of rear disc, the disc should be changed. NOTE :  Minimum thickness of front disc = 24mm  Minimum thickness of rear disc = 10mm  After fitment, the run out of the disc should be measured. (For procedure refer disc run-out measurement procedure.) The run out should be less than 0.130 mm otherwise pedal pulsation will be felt during brake application. NOTE :  Before assembly clean the mating faces of the hub and brake disc. DRUM INSPECTION :  Inspect the drum for cleanliness.  Check for crack, scores etc. Check braking surface for wear by measuring the inside diameter.  Brake Drum Standard inside diameter “A” is 206 mm.  Brake Drum usable inside diameter “A” is 207.5 mm. If it more, brake drum should be replaced.  Drum to be discarded if found cracked scored excessively or grooved.  Do not weld a cracked drum. It is unsafe and must be replaced.  Smoothen up any slight scores Heavy or extensive scoring will cause excessive brake lining wear and it will be necessary to resurface drum braking surface.
