[Jason]

he was prob braking too hard

 

[Nordonian]

he says he has been yea, will it get worse. would these crack if they were standard disks

 

[Jason]

the disk is prob warped and will need replaced

 

[VEN©M]

theres a chance the disc will break under more heavy braking.

im guessing these were probably cheaper aftermarket 'drilled' discs?

Drilled discs can be prone to cracking, grooved ones are better for road used.
