front driver side squeak

[admiral awesome]

my driver side squeaks constantly no idea what it is starts at around 20mph and it doesn't go away even when im driving highway unless the brakes are applied kind of a high pitched squeak sounds like ek ek ek ek ek ek

Your brake pads are rubbing against the rotor. Clean your brakes and the noise should go away.

That also could be a bent backing plate or a stone caught between the backing plate and rotor. If it is the pads rubbing, the caliper probably needs to be rebuilt.
