Once I had delayed the change of the disk pads and the metal part had done the damage to the disk . After that I had changed the brake pads with new original ones but after sme kms , 'squeeking' sound arises.
everytime i change the disk pads with an new ones after just couple of kms the same sound ariises.
I hav touched the disk surface, grooves hav appeared, the area of contact is not even, its groovy. Braking is not compromised in any weather condition,though.

has my disk gone damaged, can it be repaired? how? or I hav to live with it?
I aint going to replace with new disk assembly,Its not feasible for me.

Answer, Yes! Disc wears out! You have the minimum thickness value given.

@above
warranty doesnt apply to normal wear and tear of parts. unless the wear is too premature, if you've ridden 10k+ kms with the bike i doubt whether they'll agree to replace it.. try though !

but
first do this
-check the disc's thickness with a vernier's caliper
-see whether the disc is thicker/thinner than the recommended value

ZMA discs are also made by tata (tata will be embedded on the disc) and the recommended value is also embedded.

IF the disc is thicker (to a good extent) then have the disc surfaced evenly grinded to a smooth finish (so that the grooves get eliminated)

if its thinner or nearly equal to the minimum recommended thickness then change the disc.

Yes, if the wear and tear is abnormal,you can ask them to replace under warranty. Certain terms and conditions may apply though. Mail HH regarding this.
