Brake Pads and When to Replace Them

If you ensure that your brake pads are in peak condition and you change them at the correct time, you will save a lot of money in the long run. It can also help you avoid serious accidents. In this article, we will delve deep into what brake pads are and when they have to be changed. 

What Are Brake Pads?

Brake pads are a crucial component of a car’s braking system. They are in between the brake shoe (the part that slows down the rotation of the tyres by clamping down) and the brake drum. Other parts of a car, like rotors, callipers, and discs, begin to wear if the brake pads are not functioning properly. You can avoid pricy repairs and unsafe driving conditions if you keep your Brake Pad Replacement Luton in pristine condition. It is why it is necessary to pinpoint when it is time to replace your car’s old brake pads. 

What Happens When Brake Pads Wear Down?

The brake pads wear and tear by little amounts each time you use the brakes of your vehicle. For any kind of brake pads, be it metallic, ceramic, or organic, the protective coating comes off from the brake pads due to this friction. As time passes, the deterioration begins to add up – the brake pads become thinner and thinner until it needs to be replaced. We have compiled a few signs which indicate when you should change them. 

  • Squealing Or Screeching Noises

Usually, the first sign that just about any driver will notice is a whining, screeching, or squealing sound every time he or she is engaging the brakes. A small, metallic shim indicator is put in the brake pads to make this noise. If you hear this noise regularly, it is time to take your vehicle to a brake specialist for a check-up.

 A thin dust layer forms on the brake pads when brakes are left open to damp, wet weather, like after a rainstorm. The dust layer can also cause an almost indistinguishable screeching sound during braking. If you stop hearing the sound after braking a few times, it indicates that it was just due to rust build-up. You don’t need to replace your brake pads in that case. 

  • Less Than A Quarter Inch Of Brake Pad

You can conduct a visual inspection to see if the brake pads have to be changed. The car owner will see that the brake rotor squeezes the brake pad if you look through the tyre spokes. You need to get your brakes checked if the pad is not at least ¼ inch (about 3 millimetres) thick. You must do this, especially if you haven’t had a brake inspection for a considerable amount of time. 

  • Deep Metallic Grinding And Growling

Hearing a low, deep noise that sounds something like metal grinding against each other or a rumbling growl, can mean one thing – the callipers and the brake discs are making contact in addition to your completely worn brake pads. The metal on metal contact can be very harmful to the braking system very quickly. Therefore, it is paramount that you take your car to a garage as soon as possible after hearing this kind of sound. 

  • Indicator Lights

The dashboard of a few cars has an indicator light that comes on when the brake pads need replacing. Go through the owner’s manual to find out if your car has the low pad warning system installed in it. Keep in mind, whenever the light does switch on, you have to get a mechanic to change both the brake pads and the light sensors. 

  • Vibration When Braking

If you experience vibration during braking, it is a sign that you need to let a professional do a check-up of your braking system. There is a chance that the rotors are warped, which has led to uneven brake pad wear.

How Long Do Brake Pads Last?

Brake pads usually last for about 30,000 to 35,000 miles. The actual answer to this question differs from driver to driver and vehicle to vehicle. For instance, if you usually drive in heavy traffic or urban areas, you need to use brakes a lot more than someone driving on highways or in the countryside. Some drivers also have the habit of “riding the brake” – it means that they tend to press and depress the brakes more frequently than others. It causes a quicker wearing of brake pads. 

If you spot any of the symptoms stated above, get a mechanic to do a thorough check-up. If you are a bit attentive, you can easily know when you have to opt for Brake Pad Replacement Luton.
