Motor vehicles are vital and one of the most important parts of braking systems. What materials are brake pads made of? the question of each zamis a matter of curiosity. Therefore, in order for the brake systems, which are extremely important, to carry out their duties in a high quality, the brake pads must also be of high quality and give confidence.
What is Brake Pad Used in Vehicles?
Brake pads used in car brakes are made by combining many materials. The basic features sought in brake pads are wear resistance and friction coefficient according to standards. Brake pads overheat due to friction during braking. The braking effect of the tiles may change due to very high temperature or the tiles may undergo mechanical deformation. One of the parameters affecting the performance of the brake pad is the mixing time, which is one of the important factors in ensuring the homogeneity of the pad.
What Are the Functions of the Brake Pad?
Vehicle users know very well that brake systems and brake pads are of great importance for the safety of the vehicle. The functions of the brake pads within the system, which is so important, are also zammoment matters.
The functions of quality brake pads, which should be used safely in all motor vehicles, are as follows;
- Resists high friction speed in working discipline
- Friction coefficient is independent of temperature, braking pressure and speed, or the change in friction behavior is small
- Quality pads are produced resistant to high temperatures.
- Same zamIt has high thermal conductivity
- It has good corrosion resistance and high mechanical strength
- It has a low noise level and is resistant to seasonal conditions.
- It is expected to have high quality and wear resistance in order to enable vehicles to stop suddenly while on the move.
What are the Types of Brake Pads?
brake pad productsvaries according to the type of vehicle used. These are generally commercial vehicles, heavy vehicles, passenger cars, freight and passenger vehicles. same zamAt the same time, brake pads also vary according to the type of material used in production.
Brake Pad Types According to Production
Brake pads are not produced in a single type and the production may vary according to the vehicle category to be used. Although the brake pads are different, the product is taken into account in the content.
In this context, the brake pad types that vary according to the vehicle used are as follows;
- Brake pads made of completely organic material,
- Brake pads, which are more durable and made of ceramic material,
- Brake pad, which is designed to be long-lasting and made of metal material,
The materials and reasons used in the production of each brake pad are different. Each type has its own distinct advantages and disadvantages.
Those who do not want to hear the sound coming from the brake pads in their vehicles can prefer ceramic pads. Organic brake pads are environmentally friendly products and are among the most suitable and high quality brake pads. Metal brake pads are the most used pads. It is heat resistant and cools quickly. Each has different features, quality and price.
Brake Pad Production
Brake pad materials are produced with care and attention in the field of powder metallurgy. Coating materials are produced by passing through mixer, hot casting press and sintering furnace. The materials that make up the composition are first mixed in the mixer until they become homogeneous. After mixing, the materials of the mixture are poured into the mold cavity of the presses in equal amounts and shaped at a certain pressure and temperature.
Which Materials Are Used in the Production of Brake Pads?
Thickness grinding, chamfering, grooving and drilling operations are carried out with a powder-mixed grinding center that has taken the shape of the coating, and the machines used can consciously control each coating 100%. In order to prevent the effect of oxygen in the atmosphere on the lining materials at the inlet and outlet parts of the sintering furnace, a flame shield was created with butane gas. After pre-sintering, sintering and cooling processes, the coating material in the furnace is sintered by moving it on conveyor belts.
In general, the material mixture of brake pads produced in high quality is as follows;
- 20 percent resin material
- 15 percent copper material
- 5% aluminum material
Apart from these, 10 percent cashew, 5 percent graphite, 2,5 percent rice powder and 42,5 percent barite materials are used.
Quality Brake Pad Production
Brakes absorb the kinetic energy generated by the movement of the vehicle and convert it into thermal energy. By doing this, the high heat from friction must be quickly removed from the brake discs and pads. For this reason, brake discs are exposed to very high thermal and mechanical loads. Due to its features such as high wear resistance, hardness and corrosion resistance, gray cast iron is the most suitable material when considering the cost.
What is the Life of Brake Pads?
The replacement time of the brake pads mostly depends on the use of the vehicle, but also depends on the distance traveled by the vehicle. In vehicles used with the best driving, the life of the brake pads in general reaches 60 thousand kilometers. Conditions that shorten brake life, in general, are situations such as continuous city driving, continuous and rapid stop-and-go, sudden acceleration and deceleration, unnecessary continuous pressing of the brake pedal, and continuous use of vehicles on rough roads.
What Does a Brake Pad Do?
In order to better understand what a brake pad does, it is useful to have an idea of how the brake system works. In order for the brakes to work, many parts must work in harmony with each other.
Disc brakes used in automobiles; It consists of a pad, disc, jaw, piston and fittings. When the driver presses the brake pedal, hydraulic fluid travels through the piston and cables, activating the caliper, causing the pads to compress the brake disc. The brake disc placed between a pair of plates in the brake caliper is compressed and slows down due to friction.
In short, the brake pads compress the brake disc when the brake is applied, causing the vehicle to stop. In this case, where the kinetic energy is converted into heat by friction, different air channels are used to cool the disc, which is exposed to high heat caused by friction.
It has gained experience in the production of brake pads and its quality is indisputable. PWR Pads manufactures using the best materials.
