Q: When I brake it makes a loud grinding noise

asked by on

When I put the brakes it makes this loud and grinding noise

My car has 158000 miles.
My car has an automatic transmission.

Hi, thanks for writing in. This is a sign of bad or warped brake rotors. When brake rotors get hot due to friction and then col down repeatedly, they can develop low spots in them which can cause them to warp slightly. This creates an uneven surface for the brake pads to wear against. When this happens, this can cause a grinding noise and/or shaking feeling. Here at YourMechanic, we can have a technician come to your home or office to inspect and diagnose this the grinding noise issue for you, and make or suggest the necessary repairs.
