it does help but only when da drums have got uneven inner sides..... nd tat happen after thousands of miles..... groves are formed by use of cheap break shoes..... being a new car tat should'nt be da case..... check da inside od the drums by moving ur finger to feel ny groves.... if there are groves then u will have to get them treated for it... but da fact tat its only 10k km driven is strange......
