If it sounds like metal on metal it might be your sway bar. There is a bar used for stabilizing the frame and suspension that snapped on my 99 Solara and was handing by a bolt. I discovered it by hearing it clanging on the wheel when I was breaking. I detached it by taking off the bolt and it has been fine....
not usually. warped rotors will cause a vibration during braking.
warped rotor
replace front brake rotors and pads.
what would cause a rubbing noise on drivers side front wheel especially when braking ( I replaced rotor and wheel bearings are good) ?
To the FRONT of the vehicle
What percent of braking are front wheels responsible
realignment, 60 to 80 bucks
When you drive over a clicking bettle.
The pads may be worn out. have it checked out.
My guess would be that you might have a bad brake hose to one of the front calipers.
front struts berings
Most commonly it's the CV joints.
