Brakes are some of the most essential parts of a vehicle. They help control the speed or bring the vehicle to a complete stop when necessary. The brake pads work hand-in-hand with other parts in the braking system to make this possible. They are semi-metallic or ceramic plates mounted on a brake calliper. When the driver applies the brakes, the brake calliper squeezes them against the brake disc (brake rotor), slowing the vehicle down.
Like most other vehicle parts, brake pads wear out because of friction. As they rub against the brake disc, their thicknesses gradually reduce, making them less effective. Therefore, they must be replaced.
When is the Right Time to Replace Brake Pads?
The right time to replace them depends on various factors, such as their qualities, driving habits, type of vehicle, etc. However, most experts generally suggest replacing them every 40,000 to 60,000 kilometres.
You can also tell that the brake pads need to be replaced if you see the following signs:
1. Squealing Sound from the Brakes
If you hear a squealing sound every time you hit the brakes, it could be just the right time to change the brake pads. When they wear out, they no longer make full contact with the brake disc. The brake pad’s metal backing plate can rub against the brake disc, producing a squealing sound.
2. Longer Braking Distance
The braking distance is the distance a vehicle travels from the time the driver applies the brakes until the vehicle comes to a complete stop. If they are worn out, they can cause longer braking distances because they reduce the amount of friction that is produced when the brakes are applied. This can cause the vehicle to take longer to stop. It is important for a vehicle to have a good braking distance so that it can stop when required.
A longer braking distance is a sign that your brake pads could be worn out and need replacement.
3. Vibrating Brake Pedal
Worn-out brake pads can cause a pulsing sensation or vibrations on the brake pedal when the brakes are applied. This is due to the metal backing plate rubbing against the rotor caused by uneven wearing out of the brake pads.
