Q: Brake problem

asked by on

I hear grinding sound when pressing brakes.

My car has 186000 miles.
My car has an automatic transmission.

The most common cause to hear a grinding noise when pressing the brake pedal is worn brake pads. The friction material on the brake pads will wear out over time and the metal plates that the friction material is mounted to will come into contact with the brake rotors, thus causing a metal on metal grinding noise. There could be some kind of foreign material caught inside the brakes, or it could be noise from a low quality set of brake pads, but the most common cause, by far, is worn out brake pads. If this is something you need to have diagnosed and/or repaired, consult a certified mechanic, like those available at YourMechanic.com.
