Disc brakes make a grinding sound

Asked by: Diana Ortiz

Scraping or grinding noises occur if the brake rotors are not correctly centred between the brake pads. This is often because the brake callipers are not exactly centred. To fix this, loosen the screws securing the calliper onto the fork/frame, and pull the brake lever.

Why are my disc brakes making a grinding noise?

If your brakes emit a sharp grinding sound while braking, it’s likely that the brake disc and the caliper are rubbing together. The sound is usually heard when you stop your car, but you may also feel the brake pedal rumble as you step on it.

Why do my brakes grind but pads good?

Your brake system could have debris from the outside get lodged in it. This debris could be a piece of rock or gravel that gets stuck in the caliper. Then, the debris will rest between the rotor and caliper, and cause scraping or grinding noises to occur and possibly vibration.

Can brakes grind while driving?

Brakes that are worn down to the backing plates can produce a grinding noise when driving. Severely worn brake pads or shoes can create a grinding noise while driving. The problem happens when the brakes are worn down to the backing plates (or wear indicators), allowing for constant contact with the drum or rotor.

Will brakes grind if fluid is low?

Uneven brake pads: When the brake fluid gets low, the pedals cannot depress brake pads with the same amount of pressure. This causes uneven wear on the pads. In turn, you experience squeaking, squealing, and grinding when you apply the brakes. The vehicle may also rumble and vibrate when you use the brakes.

Why do my brakes grind at low speeds?

As a general rule, noise when braking at low speed can be caused by worn out brake pads, worn or warped rotors, trapped dirt or rust on the brakes and sticky brake calipers. If you are hearing a new noise when braking or the brakes feel different, then it’s a good idea to get them checked out as soon as possible.

How long do brakes last after they start grinding?

New brakes must be worn in by use and may make a grinding or squealing noise right after installation. However, you should notice that the grinding sound disappears within a few weeks as the brakes are worn in. If the grinding persists after about 50 miles, consider taking your car back to the shop to get checked.

Why are my brakes grinding after new pads and rotors?

A: Unless the rotors are worn beyond the mandatory discard thickness, we prefer to replace the pads only. Not only does this obviously save money, but time. New pads must be burnished into new rotors before the best braking performance is achieved.
