I get an anusual grinding sound/vibration when i break sometimes, can't tell if it's when I'm turning or breaking, but usually happens when breaking AND turning.
loose bearing bolt?definitly check that first..pull that center cap cover on the tire off and make sure its real tight!!!then check lugs,outer control arm joints ,balljoints,caliper bolts...strut bolts
if it just needs brakes maybe,,,if your pedal pulses or your wheel pulses when you step on em,,warped rotars!!gring could be the sensor on the pad that tells you they are low...its a metal claw that scrapes the rotar when the pad gets worn down...
good luck
