1. The rotors were not turned i.e smoothed down with a tool, and they are wearing the pads into the shape of the rotor grooves,
or
2. there was no lubricant applied to the pads when installed (to stop noise)
or
3. Nearly worst case - a pad fell out.
4. Something really bad - take it back to see a mech.
Some things to look for - Stop the car, turn all the way left. Turn off the car, get out look under at the pads (they're the things that make contact with the rotor attached to the hub next to the tire) on the passenger side -see that they are still there. Turn all the way right, get out look under at the pads on the drivers side.

buy new brake pads
It is not good if a persons newly changed brake pads are grinding. To stop this, a person needs to change the brake caliper pressure.
A grinding noise when braking can occur when the brake pads are going bad. You are hearing the brake grinding on the metal discs.
you probably need a new set of break pads. they have most likely worn down to the metal so that'd be why its grinding
lol change your brake pads they make a grinding noise when its time to replace
your brake pads are probley wore out so its grinding on your rotor
brake shoes or pads are worn and need replacing
A grinding noise in the wheel will either be caused by worn brake pads, or a defective wheel bearing. Remove the left front wheel and inspect brake pads. If the brake pads are OK, you will need to remove the caliber and inspect the wheel bearing.
Sounds like you need a new set of brake pads and might have to get the rotors turned. Sounds like you need a new set of brake pads and might have to get the rotors turned.
your brake pads have worn out, so i would get some new ones if i were you.
Something is very wrong. Either defective brake pads or they were installed incorrectly. Have them inspected immediately.
This is often caused by installing new pads on worn or slightly worn rotors. Buying new rotors or turning the same rotors would make a smooth surface for the new pads to rub against. Any surface that is less than smooth will cause some grinding for a few days or maybe longer. It also shortens the life of your new pads.
