hi my 2011 dec Linea has clocked 24600kms..for last 2 months im having a problem that im hearing a hissing/whistling sound from the front RH tyre while braking. i visited SC and they cleaned the brake pads and for 1-2 days it was ok,then again the sound has come. last week i again visited SC and they told that brake pad has been worn out, and changed the same.again the sound had gone for 1-2 days..after that while my drive to Cochin i faced another problem that a grinding sound from from RH side while braking,both in parking speed and normal driving along with this whistling sound. after my trip i again visited th SC and they told there were scratches on brake discs and they skimmed it from lathe.after this i can feel the grinding sound in a very minimal level,that the SA couldn't feel.and the whistling sound also comes very occasionally also in a minimal level any one experienced such a problem??pls help P.S : i have changed the brake discs twice in warranty period due to steering wobbling while braking.last time changed was on december 2013 and i had driven only around 5500kms after that.
