It sounds like you need to check your front brakes. Most of the braking is done with the front brakes, therefore they tend to wear out more quickly than the rear brakes. If you let it go too long, you will need to replace the rotors as well. Have the brakes checked ASAP as this is also a safety concern for you and others on the road. I suggest having a certified technician, like one from YourMechanic, inspect your braking system to determine the exact cause of your concern.

If your brake pads are excessively worn, the metal backing on them can become exposed, allowing the rotors and metal to grind against each other when you brake. Not only does this cause an unpleasant sound, but it can also damage your rotor, reduce your brakes` responsiveness, and lead to brake failure.
If you hear grinding noises when stopping or slowing down, your brake pads are most likely the issue. Remember, over time your brake pads lose their thickness and begin to make squealing noises known as “brake scrubbing.” As your pads wear down further, you`ll hear a grinding noise instead.
If you hear a grinding sound coming from your brakes, it`s usually a sign that your brake pads are worn out and their metal backing plates are rubbing against the brake rotors. When this happens, your brakes won`t be able to function properly, which can increase your stopping distance and make you more accident-prone.
Noises When the Vehicle Brakes
Warped rotors can cause a squeaking noise when the brakes are applied. They can also make a scraping or grinding sound when they`re warped and worn down. The squealing noise, however, can also be made by brake pads that are worn out.
Driving with grinding brakes is simply not safe. Brakes are a critical component of safe driving and should not be overlooked. If your brakes start to fail: Don`t drive any further.
One possible cause is debris or dirt stuck in the brakes, which can create friction and lead to a grinding noise. Another potential reason is a misalignment of the brake calipers, causing them to rub against the rotor instead of smoothly pressing against it.
Even if you replace the pads or rotors, bits of debris can get caught up during the repair process. This should go away as you continue to drive your car. If you`ve only had your brake pads replaced and not the rotors, the grinding noise could be coming from worn-out rotors.
If your rotors are faulty, they may produce a squeaking, squealing, or grinding sound when you apply the brakes. Warped rotors usually emit a high-pitched squeak, while severely worn rotors tend to make a scraping noise.
Scraping or grinding noises you hear while driving or turning can be caused by the following issues: Worn or failing brake parts: Unevenly worn or rusted rotors or worn or thin brake pads. Worn dust shield that`s moved closer and contacting the brake rotor. Loose, worn, damaged, or failing wheel bearings.
Grinding noise when braking
Grinding brakes indicates that your brake pads have worn all the way down and are now grinding metal on metal against the rotors. The damage can be pretty intense, so you are probably in for a complete new set of pads and rotors.
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.
Early on, it might sound like something is rubbing when you let off the brake pedal. Ignore that and you will eventually hear a metallic grinding, scraping, or rubbing sound that indicates metal-on-metal contact in your brake system. A less-common occurrence is the sound of a “clunk” when you hit the brake pedal.
Using data provided by Federal Highway Administration statistics on how many miles people drive annually, typical brake pads will last between 3 and 7 years. Brake rotors last roughly 70,000 miles, but they need to be inspected for uneven wear.
You`ll receive a warning squeal as the pads wear away–right before the metal backing plate starts rubbing against the brake disc. This causes a very loud grinding noise (metal on metal) whenever you put your foot on the brake. If it gets to this stage, your car is now dangerous to drive.
Brake pads that are severely worn down often leave deep, circular grooves in the rotor. If such grooves are visible, brake pads and hardware must be replaced, and rotor service or replacement will also be needed.
If you have an open-spoke wheel design, you can run your finger vertically down the brake rotor friction surface. If you can feel and see noticeable grooves, then it`s time for new brake rotors. For cars with hub caps that don`t expose the rotor, you will need to remove your wheel to inspect your brake rotors.
When your brake fluid is dirty or low, it isn`t able to depress your brake pads as efficiently as it should. This can cause uneven wear or even damage to your brake pads, which can cause grinding, squeaking, or squealing noises when you use your brakes.
Worn, missing or broken brake caliper hardware, especially mounting bolts and shims, can cause grinding two ways: A brake caliper not fully secured to its support bracket because of loose or damaged hardware can drag and rub on the rotor, producing a grinding noise while driving and stopping.
WD-40 Specialist Automotive Brake and Parts Cleaner is safe to use on clutch and brake assemblies, brake discs, callipers, brake drums, brake pads and brake linings.
Rotors are very capable of lasting more than 100,000 miles with proper brake inspections, maintenance, and brake pad changes. When brake rotors are replaced, it`s advised to replace all of them and brake pads at the same time.
The most surefire way to determine if they are at the end of their life is to measures the physical thickness to determine if they are too thin. The minimum thickness is defined in the vehicle`s service book, and some brake rotor manufacturers even engrave it on the rotor`s surface.
