What is the Grinding Sound When I Brake?


what is the grinding sound when I brake

We’re all used to the unique sounds our cars make, so when a new sound starts, we take note. If you’ve noticed your brakes grinding, it could be a foreign object lodged in the brakes, or your brake pads are worn through. If you’ve noticed this sound when braking, be sure to bring it into our service center to make sure your brakes are working as they should.

Our expert team at Harr Toyota, serving near the Worcester, Auburn, and Shrewsbury, Maryland, areas, is here to help explain what your car’s brake sounds mean and what to do about them.


The Brake-sics

Before you can start looking into specific issues, it’s best to know the basics. A lot of cars have disc brakes, which means there’s a rotor—the “disc” in “disc brakes”—brake pads, and a caliper. The rotor spins with the wheel, and when you brake, the caliper squeezes the brake pads against the rotor. This causes friction and makes the car slow to a stop.

What is That Grinding Sound?

The likely option if you hear a grinding sound when braking is that the brake pad is completely worn through and the rotor is scraping against the caliper. If this is the cause, you should get your car into our service center as soon as possible, where we can check to see if your pads are worn out.

On average, you should be getting your brakes checked every 10,000 to 20,000 miles. Your brake pads should be replaced every 40,000 to 50,000 miles, and your rotors should be replaced every 70,000 miles.

If you’ve just changed your brake pads and there’s still a grinding brake sound, it could be a foreign body lodged in the calipers. This issue can often be fixed by driving the car back and forth until the object is dislodged. If the object cannot be dislodged, you should take your car into a service center.


Causes of Brake Wear

What Causes Brakes to Wear?

Brake wear is completely normal. Brake wear is not an exact science, but it is caused by everyday driving, so the more you drive, the more quickly your brakes will wear.

If you want to extend the life of your brakes, drive with the flow of traffic and leave plenty of room between you and the car in front of you to avoid a hard brake. Braking hard, especially at higher speeds, can cause more friction and faster wear.

If you are experiencing signs that your brakes are worn, you should schedule a brake inspection.


What’s Entailed in a Brake Inspection?

A brake inspection should likely be 30 minutes or less, with repairs and replacements adding extra time. During that time, the entire brake system will be checked from the rotor to the brake lines. If you think you need a brake inspection, you can schedule your service online through our service center page.
