In case of hard braking with ABS
,slight vibrations occur in the cars.
About noise,some cars have it too,but if noise is higher then maybe the brake shoes need replacement.
Oh,have I read wet roads?If yes,then no issue it is.
Just get the brake shoes changed if you feel it too odd(just to make your mind happy).Else this is really no serious issue.
And still if you feel uncomfy,then go to Maruti A.S.S.
