is it the khar khar noise annoying you ? the noise comes from brake caliper guide pins sometimes. after prolonged wear and tear, there is a little play that produces noise even on little bumps and potholes.
I initially thought it was from steering rack but one day I was just having look at the front disc brakes and the caliper pins. I pushed the the rubber sleeve on the pin inside (it had actually moved outboard and was little worn out) and for next 300 ~ 500 km the noise stopped.
It is my assumption only. I plan to to get them checked and greased with silicone on my next visit to mechanic
will revert back if it resolves the issue
