Your brakes are probably getting low and they are rubbing against the rotor.
Probably worn out brakes. Could be wheel bearing or other worn components also. Check for looseness before you drive any further.
what would cause a rubbing noise on drivers side front wheel especially when braking ( I replaced rotor and wheel bearings are good) ?
Failed brake line.
Could be lube/oily substance on the pads.
exhaust leak driveshaft center bearing mudflap/fender skirt rubbing tire engine mount
start bleeding at the passenger side rear wheel then go to the drivers side rear wheel, next to passenger side front wheel and finally the drivers side front wheel, this is the order you should bleed the brakes.
Worn bearings, loose rotor, warped brake rotor, sticking brakes.
Passenger rear, drivers rear, front passenger, and then drivers front.
You have two choice's, Brakes or Bearings both require immediate attention. So get it to a qualified person ASAP. Good Luck and Remember.Change Your Mind, Not Your Oil.Use the First In Synthetic Motor Oil's.See My Bio For Information & Contact Details.
Depends on where in the front... could be breaks, something in the wheel/wheelwell
I had the same problem. It was the upper control arm bushings. They got worn and slapped back and forth when I hit the brakes.
