If your brakes are making a grinding noise when you push the pedal, this can be the sound of a problem with your breaks. Before anything, you should get it fixed as the breaks are the only way you can control your car’s speed. Coming back to the grinding noise, it can be caused by several factors. Here we have mentioned some of those factors.
Worn out brake pads
If you hear a grinding sound when you press down on the brake pedal, your brake pads may be worn out. Metal comes into touch with the metal on the rotor when the backing plate loses its substance. It’s also possible that the brake calliper is making contact with the rotor.
Your brakes could be seriously damaged if the pads are not replaced, regardless of which one it is. The backing plate has the potential to harm your rotor, resulting in damage and grooves. The calliper will then be subjected to the same treatment as the rotor. When your brake pads wear out, you should replace them as soon as possible.

Worn out shims
You must change the shims if you have a brake job done or replace brake pads yourself. If you want to have your job done quickly, bad mechanics may try to dodge this, so make sure they replace them.
Brake shims that aren’t replaced will wear out over time. A piece of the brake shim may come into touch with the rotor or another metal component of the braking system as a result of this. As you drive the vehicle, you will hear sounds from your braking system due to metal touching metal like this. As a result, make that the shims are replaced.
Worn out rotors
Brake rotors that are worn or damaged (warped, gouged, or fractured) will generate a variety of noises. Squealing or squeaking noises are produced by bent or non-flat rotors. Scraping noises may be heard instead if the rotors are overly worn.
Furthermore, worn rotors will cause a great deal of braking system vibration. The vibrations may occur in erratic patterns, which your foot will feel through the brake pedal or your steering wheel will tremble. If rotors are somewhat deformed, they can be resurfaced (or rotated), but rotor replacement is required if they have simply outlived their usefulness.
Lack of lubricants
When installing brake pads, lightly grease the backside of the brake pads with brake calliper lube. If this easy step is skipped, the metal of the brake pads and the metal of the calliper piston will collide when the brakes are applied, causing screeching or rubbing noises. Before reinstalling the brake calliper, make sure the calliper slider pins (which join the two sides of the brake calliper together) are well greased.
