Asbestos and Non-asbestos brake pads

Brake pads are one major spare part in the braking system for automotive business.
Brake pads contacts and applies pressure and friction to a vehicle's brake rotors. The pressure and friction applied to the brake rotor is what slows and stops the wheel.
In the past, brake pads have an important ingredient which is " Asbestos" because it is cheap. When the brake soot comes out with white powder, it does not feel dirty at the wheel and absorbs the noise.

It looks like asbestos has a good ingredient to produce brake pads but indeed it’s dangerous for your health. Risks from using Asbestos brake pads, after stepping on the pedal to stop the car, the soot from brake pads will cling to follow the wheel, rock fibers may fly into the car.

The drivers or passengers will inevitably receive asbestos, which accumulates asbestos as the source of Asbestosis
International brake pad manufacturers in the world have abolished asbestos production in accordance with legal regulations. Environment and the standard of the automobile industry.

Today, many automotive manufacturers around the world Including Valeo denied using asbestos to produce brake pads .

Disc brake pads are an important part of all the automotive without which we cannot imagine them to be completed systems. Brake pads are currently on the Asean market can be divided into 2 major groups as follows

1.Disc brake pads are generally low cost containing Asbestos. 

Asbestos is an old brake pad technology that uses asbestos as the main component. The special features are Asbestos substances are cheap and provide good friction at low temperatures but it’s harmful for the respiratory system.

Therefore there are many countries that have banned the production of this type of brake pads.

 

Asbestos give braking properties can be used at low speed or at an early stage but when the speed is higher braking efficiency will decrease quickly and most importantly, the service life will be short. The disc brake pads run out quickly. In addition, asbestos affects health.

Currently, there is less use or banned in many countries since asbestos is dangerous for handling due to health hazards and environmental impact.

 

2.Since asbestos is hazardous to health. Therefore, there is scope for replacement and brake pads manufacturers were invested and developed technology have proposed materials for asbestos replacement as the basic material for brake friction materials.

Disc brake pads that does not contain Asbestos or Asbestos free group that can be divided into 3 types of technology

  1. Non-Asbestos Organic (NAO)
  2. Semi-metallic
  3. Low-metallic

The key features of asbestos replacement technology are as follows but would be different in percentage to serve in difference choice and match with driver needs.

  • Stability and braking efficiency 

  • Braking at cold and high temperature 

  • Pedal sensitivity 

  • Wear resistance 

Even the cost of production for non-asbestos technology will be higher than asbestos.

However, well ordered research has been set in several industrialized including brake pads, many manufactures to substitute asbestos fibres in many recent applications, because of distinguished health risks to users

Valeo Service braking systems are designed to provide comfort in road safety.  Valeo utilised the best possible Non-asbestos technologies to give you safety and comfort for each application. Choose Valeo brake pads to match with your vehicles and your driving needs.
