When you have an issue with the brakes of your car, it usually gives more concern. This is because brake problems can be very risky, as they could cause fatal accidents and lead to loss of lives and destruction of property. You won’t be able to stop your car in time. 

Grinding noise when you’re braking cause be caused by two main instances. The main reason why your brakes are grinding because your brake pads are worn down which causes friction between the two components. These malfunctions come with obvious signs. Whether you are a novice or not, you can tell when your brake is beginning to lose its function. You can easily tell from the grinding sound they make. And when you begin to hear these sounds, must be followed up for your own safety.

What Is Grinding Braking?

When you hear a grinding noise while braking, it simply means that your brakes are malfunctioning. Brakes are one of the most essential systems of your car and as such should be given proper maintenance.

Most motorists tend to ignore brake noises for long. Not all brake noise should be neglected, especially the grinding noise. Brakes grinding noise are sounds heard each time you press your brake pedals. It sounds like when you shake a can with stones in it. Sometimes these problems pop up, your car will be unable to stop.

Brake is one component of a vehicle that does the hardest job. Each time you stop your car, they are exposed to forces and generate excess heat. The amount of friction made each time you stop your car is enough to make the brakes develop a fault.

Some of the possible causes of grinding noise from brakes could be when dirt gets lodged in the brake system. These first could be a tiny rock stuck in the caliper. There, it sits in between the rotor and caliper. So, whenever you press the pedal, you hear a grinding noise. And this noise will continue even when you don’t press the pedal, as long as the dirt stuck in it isn’t removed.

Another cause of this noise is when you don’t drive your car frequently. Brake pads last from 30,000- 70,000 miles, depending on the model of the car and driving method. When the brake pads are not used for long by driving your car, they could get rust and corroded. And because of these rusts, the rotor gets affected and may require resurfacing.

How To Diagnose Brake Screeching Noise?

Understanding the car brake system is mandatory in order for you to diagnose a possible brake problem. Identifying some signs will help determine the brake’s fault before time and find a solution to it before it gets worse. 

Some of these brake issues can be recognized from the abnormal response and its scratching and screeching sound.

Abnormal Symptoms & Responses

The health of the brake system of your car shouldn’t be compromised. You must give priority to all the signs and indications that suggest the braking system of your vehicle is failing. How would you hold the brake in suspicion? 

Let’s check out some of the common signs that could be responsible for the unhealthy, grinding noise from your vehicle brake system:

  • Car Doesn’t Stop on Time

If your car travels too far and fails to stop minutes after applying the brake, it’s time to take a break and do some adjustments on the brake or replace the brake linings. Usually, a vehicle isn’t supposed to travel more than an inch or so before coming to a stop. If this persists, the grinding noise is inevitable. 

  • Car Pulls to One Side

When you notice that your vehicle pulls to one side when you press the brake pedal, then you need to check the brake fluid. It may be that the stuck caliper is having a crisis.

  • Pulsating Brake Pedal

Another sign that your brake needs diagnosis is when you observe a pulsating pedal when you put the car to a stop in an emergency situation. It is possible there’s a lateral run-out, caused by overheating.

Steps to Diagnosis Grinding Brakes

  1. Check the fluid level, hoses, and lines for leaks 
  2. When cylinders and brake calipers do not move freely or the seals are brittle and not dry.
  3. When the brake pedal becomes hard, or soft when pressed or lives faster than usual, it could be hydraulic system related.
  4. If braided lines become firm, cracked, or brittle, instead of being flexible.

These are an abnormal response from the brake system to diagnose. Then for the screeching sound from brakes could be a result of the car idling, this can form rust on the rotor. A grinding sound heard when using the brakes, which can be related to work down the brake pedal or disc rotor. Also, on the disc pad, check for any form of rust on the ‘I wear’ indicator.

So, it’s best to get them replaced. 

If you experience squeaky brakes, you will need to machine the brake disc or drum. It’s likely they’re loose, missing, or damaged. Alternatively, you can check the brake linings to see if they’re worn. Shock absorbers may also be the issue with your car.
