It sounds to me that either the brake pad has shifted and isn't seated properly in the caliper OR the bolts that attach the caliper may have been installed incorrectly and are rubbing against the dick rotor. One more thing, the backing plate (thin piece of metal that blocks and protects the inside of the rotor may be bent and rubbing on rotor.
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.
The grinding noise you hear are your shocks and struts. If you experience bouncy while you are driving, as well, you should have them changed.
Check the front brakes. the most common problem for grinding is worn brake pads allowing the metal backer to rub the rotor.
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.
i have a grinding noise on the front left wheel. i have taken the calipa off and i have one brake pad that is shot. could it be that or can it still be the bearing. how can i find out.
The grinding noise is the brakes pads proably the noise is in the front. The front brake pads are easy to replace and is a do it yourself sort of thing. My guess is your brake light is coming on because of this condition. I assume your brake light has been coming on for a little while now.
Air in the system. Bleed the brake system.
possibly brake pads worn down
Have you had a front-end alignment? When you remove parts from the front end, you need to have this done.
Check for rusted brake parts, and also for partly seized bearing plates on the front struts, causing them to turn in a rough or jerky fashion. Sometimes the struts can be greased but often they need to be replaced.
Grinding noise is metal to metal contact between the brake pads and brake rotor or break shoe and brake drum. Prolonged contact between metal to metal can result in front or rear brake failure.
Diod you check front brake pads
