Rear Disc Brakes Cracked

[Shikkaka]

Hi everyone,

The drivers side rear disc has cracked for the second time in 1 month. I had them replaced and now its gone again. Any ideas what could be causing this?

Cheers

sticking caliper?
over-torqued wheelnuts?

Saying that, it does sometimes feel as if the hand brake is on but goes away pretty quick. Better get it checked.

Would this mean the caliper just needs adjusting or new caliper?
