Brakes Making Grinding Noise

When the brake is applied there is grinding noise coming from the brakes. When brakes are making grinding noise while the brakes are applied, this indicates excessively worn brake linings.

The brake lining was excessively worn down and nothing left but an exposed metal which rub against the disc or the drum depending on the location where the grinding noise is heard when applying the brake which resulted into a grinding noise.

Why do brakes make a grinding noise

(1) Excessively worn brake lining.

Car Troubleshooting

The brake linings are worn down to the metal and they are rubbing against the disc or drum (i.e. depending on if grinding is coming from front or rear) when you apply the brakes; this results in the grinding sound you are hearing. In other words, they are worn to the bone, there is nothing left, and they have been neglected too long.

What to do?

Your car's brakes have been neglected and as a result, it could be expensive to fix. First, you'll need a new brake lining. Second, you'll need to at least have the brake discs or drums (i.e. depending on if grinding is coming from front or rear) machined to smooth out the damage done by the grinding. If the damage is extreme, the mechanic may suggest new discs or drums (i.e. again, depending on if grinding is coming from the front or rear).

This is what happens when the vehicle maintenance schedule has been neglected for a very long time. To fix this problem replace the brake linings with new one then bring the affected brake disc or drum to the machine shop for machining, this is because of the metal to metal contact probably the disc or drum has been damage so it is necessary to smooth out the damage incurred.

If the disc or drum is extremely damage and machining is not possible then replace the affected disc or drum with new one. This problem is expensive to fix therefore it is important to follow the regular maintenance schedule of the car.
