Signs It's Time to Change Your Brake Pads

Change Your Brake Pads

Worn brake pads cause hundreds of accidents yearly, many of which could have been prevented by car owners regularly replacing unsafe pads. Knowing when it’s time to change your brake pads can save your life and the lives of your passengers.

Expert opinions vary, but you should schedule a trip to the motor mechanic every 30,000 km to 75,000 km, depending on factors such as your car's make and model. 

But factors like your driving style and the road conditions can also affect brake pad wear and tear. So, how do you know when to have your brake pads checked?


What are Brake Pads, and How do They Work?

Modern brake pads are similar in form and function to those invented in 1898 by Elmer Ambrose Sperry. Brake pads apply pinching pressure to the rotors attached to your wheels and cause friction, which slows and stops your vehicle.  

The material used in modern brake pads has received an upgrade from those designed in the 1890s, and today, drivers can choose from several popular varieties. 

Organic brake pads are cost-effective and are widely available as Original Equipment Manufacturer (OEM) parts. Semi-metallic brake pads are the most common and expensive ceramic pads and are the choice of many owners of high-performance vehicles.

So, what happens when you press down on your brake peddle?

  1. A cylinder sends fluid through hoses down to the callipers.
  2. The callipers activate your brake pads.
  3. The pressure on the brake pedal will determine the force of braking.
  4. The brake pads are engaged and apply pressure to the rotors in each wheel.
  5. Easing off on the brake pedal causes the process to reverse.


Signs you Need to Change your Brake Pads

Keep an eye (and ear) out for these warning signs.


Brakes are Making a Grinding or Screeching Sound

If you hear shrieking or squealing each time you apply your brakes, visit your dealership or motor mechanic.

A grinding sound (like metal-on-metal) means that your brakes are unsafe and damaging your rotors. If this is the case, then your brakes are in urgent need of replacement. 

Thinning Pads

Look through the spokes of your tires, and you will see your brake pads. They are overdue for replacement if they are less than half a centimetre thick. Don’t rely on odd sounds to guide when you should replace your brake pads.  


Dash Warning Indicators

In some modern automobiles, a dashboard light may indicate brake pad problems. If you see an unfamiliar dashboard warning light, check with your dealership service department (or check your owner's manual).


Noticeable Vibration

If you press down on the brake pedal and notice unusual vibration or shaking, your brake pads may need urgent replacement. In cases like this, your stopping distance will be affected and your brakes might be in danger of complete failure.
