When we think about motorized vehicles, one aspect that is often forgotten is the braking system. However, it cannot be denied that the braking system is one of the most important parts of driving safety. In the midst of modern speed and mobility, understanding the function of brake pads is crucial for every driver.

Brake linings are vital components in a vehicle’s braking system, playing a vital role in converting kinetic energy into thermal energy, thereby slowing or stopping the movement of the car. However, the function of brake lining is not limited to braking; it also affects vehicle control and the safety of the driver and passengers.

In this article TransTRACK , we will take a deeper dive into the functions of car brake linings, signs that brake linings need to be replaced, as well as the importance of regular braking system maintenance. Let’s explore how a good understanding of brake lining can improve driving safety and extend the life of your vehicle.

Function of Car Brake Pads

Car brake pads are one of the important components in a car’s braking system. Its main function is to convert kinetic energy into heat energy through friction between the brake lining and the brake disc or drum, resulting in a braking force that can slow or stop the movement of the car.

Here are some functions of car brake lining:

Converts Kinetic Energy into Heat Energy

When you brake your car, the brake lining presses hard against the surface of the brake disc or drum. This creates friction between the brake lining and the braking surface, which converts the kinetic energy of the car into heat energy. This process is called energy conversion. The heat energy generated by friction is what ultimately slows or stops the movement of the car.

Increased Braking Force

High-quality brake pads are capable of generating greater braking force. This can help reduce vehicle speed more quickly, even in sudden braking situations. Good brake pads are also able to handle heat more efficiently, so they do not suffer from performance degradation when used repeatedly or under intense braking conditions.

Improving Safety

The primary function of brake linings is to improve driver and passenger safety. Effective braking allows the vehicle to stop in time, avoiding collisions or accidents. Good brake pads also help prevent brake “fading”, a decrease in braking performance due to excessive heat, which can be dangerous when driving downhill or in heavy conditions.

Optimizing Driver Control

Responsive brake pads give drivers more control over the vehicle. They can adjust the vehicle speed more precisely, and brake or release the brakes smoothly according to the situation at hand. This is important to avoid skidding or slipping, especially when encountering slippery road conditions or difficult terrain.

Braking System Maintenance

Brake pads also play a role in maintaining the overall health of the braking system. Worn or damaged brake pads can damage other parts of the braking system, such as the brake discs or drums. Therefore, regular maintenance and timely replacement of brake linings are essential to maintain the performance and safety of a car’s braking system.

Thus, car brake lining is not just a component that functions as a vehicle stopper, but also has a very important role in the overall safety and performance of the car.

Signs that the Brake Pads Need to Be Replaced

Signs that the brake lining needs to be replaced are as follows:

Squeaking Sounds

If you hear a squeaking or scraping sound when braking, it could be a sign that the brake pads are worn out and need to be replaced. The noise is usually caused by direct friction between the thin brake lining and the surface of the brake disc or drum.

Disc Plate Damage

If you notice significant damage or wear on the disc, this could be a sign that the brake lining has been subjected to excessive friction or uneven pressure. This can happen when the brake pads are too worn and ineffective in slowing down the car, causing direct friction between the brake pads and the disc.

Brake Pedal Feels Vibrating

If the brake pedal feels like it’s vibrating when you brake, this could be an indication that the discs or brake drums are not rotating smoothly due to wear or damage. This can be caused by worn or uneven brake pads, leading to an imbalance in braking.

Lack of Maximal Braking Function

If you feel that your car’s braking function is not optimal, for example, it takes a longer braking distance than usual to stop the vehicle, this could be a sign that the brake pads are worn or not working properly. Worn brake pads are unable to generate enough braking force to slow or stop the car efficiently.

If you experience one or more of the above signs, it is advisable to have your car’s braking system checked by a trusted repair shop immediately. Regular inspection and timely replacement of brake pads are important steps to maintain driving safety and overall car performance.

In maintaining vehicle performance and safety, braking system maintenance is a must. By understanding the importance of brake lining function and the signs that brake lining needs to be replaced, you can take the right steps to keep your car in optimal condition.
