Тормозные колодки play a pivotal role in the safety and control of automobiles. Although conventional тормозные колодки have been popular in usage, it suffered lesser heat resistance and longevity issues. This has resulted in exploring carbon advanced ceramic materials such as carbon ceramic brake pads that are lightweight and durable.
What are brake pads and What are brake pads made of?
Тормозные колодки are components housed in a calliper whose friction surfaces aims at the brake rotor allowing car to stop. Brake pad materials tend to be different with respect to the requirement or application subjected on. A good тормозная колодка safeguards the wheel from excessive wear and tear.

Types of Brake Pads: An Overview
Керамические тормозные колодки
Керамические тормозные колодки form an integral component for the high-end supercar as they handle the harshest stops. They are denser, durable and possesses copper fibres in them that increases friction and thermal conductivity. Ceramic brake pad material produces little to no noise when applied and produces lesser dust upon degradation. Керамические тормозные колодки also cover broader driving conditions and temperature range.
Although the merits are numerous, lets discuss the ceramic brake pads pros and cons. Керамические тормозные колодки foreruns on cost perspective and is expensive among all the brake pads available in the global market. As copper and ceramic cannot absorb the entire heat on braking, the braking system here tends to degrade over time. They are also not suitable for harsh environmental conditions such as cold whether.
Полуметаллические тормозные колодки
Semi metallic Brake pads are different from fully metallic brake pads with 30% to 70% presence of metal in it. The metals are steel, copper, Iron and certain alloys where the metals are combined with a graphite material. Полуметаллические тормозные колодки are suitable for commute to higher end racing. Полуметаллические тормозные колодки are a sure choice for performance driven drivers as the metal conducts good amount of heat.
Полуметаллические тормозные колодки also suffer from certain shortcoming as they tend to be noisier compared to organic or ceramic brake pads. Полуметаллические тормозные колодки tend to put more strain on the braking system and the rotor gets degraded. They also tend to produce more debris and has cost in between organic and керамические тормозные колодки
Semi Metallic Brake pads VS ceramic brake pads: A comparison
The major differences between ceramic and полуметаллические тормозные колодки are given below for reference:
- For performance vehicles used for racing, towing and other high-end activities most drivers prefer Полуметаллические тормозные колодки
- Полуметаллические тормозные колодки offer braking over a wide range of temperatures and conditions.
- The conductivity and the ability to withstand high temperature makes полуметаллические тормозные колодки perform well and cool down quickly.
- Цена полуметаллические тормозные колодки меньше чем керамические тормозные колодки
- Керамические тормозные колодки are quieter and poses no issues to the braking rotor due to its nature of quick recovery.
- Upon wearing керамические тормозные колодки create finer dusts than полуметаллические тормозные колодки and hence create lesser vehicle debris.
Traditional metallic brake pads
Similar to semi metallic brake pads, metallic brake pads are also made up of metals such as steel, or alloys. They are popular due to their affordability and reliability however the material underperforms in harsh or demanding situations. Металлические тормозные колодки are heavier when compared to other brake pads which has a negative impact on the performance of vehicle.
Traditional metallic brake pads are prone to degradation under higher temperature or intense braking. The wear and tear caused would further reduce the friction of the braking pads leading to lesser braking efficiency. With time metallic brake pads undergoes wear and tear, hence the replacements are frequent in vehicles with metallic brake pads.
Карбон-керамические тормозные колодки
Карбон-керамические тормозные колодки are generally made up of carbon fibres and ceramic materials. They were manufactured to overcome the limitations of the traditional metallic brake pads. Карбон-керамические тормозные колодки are lightweight which is the key to the excellent performance in aerospace and racing. The lightweight nature also helps in the overall acceleration of the machine and efficient fuel consumption.
Карбон-керамические тормозные колодки are superior in offering performance in energy intensive braking application. They are able to withstand a temperature of 1000 degC or above. Unlike metallic brake pads, carbon ceramic brake pads don’t undergo degradation under high temperature application due to its thermal stability.
Карбон-керамические тормозные колодки are highly durable, they resist corrosion, wear and tear. This helps in saving the overall replacement cost related to the braking system of vehicles. The very built of углеродно-керамические тормозные колодки offers consistent performance that makes them remain stable throughout their lifespan. The friction coefficient of the material remains constant which aids the emergency stoppage of aircrafts or high-speed vehicle.
What constitutes carbon ceramic Brake pads?
Ceramic materials are rooted to aerospace and rail industries due to their extreme strength and heat resistance since years. Карбон-керамические тормозные колодки are chosen in high-performance vehicles where thermal heating, corrosion and stability poses a threat. Carbon composite brake pads are generally made from Carbon and Silicon fibres.
The carbon and silicon resin kept in mould and subjected to temperature and pressure of 4000 degC and 44000 pounds. The material is then cooled to 1800 degC and further temperature reduced by adding silicon powder into the mix. Later the mix is heated to 3000 degC under vacuum which results in the bonding of silicon carbide with the fiber. The resulting material is the high-performance тормозная колодка component of Carbon ceramic.
The cars using carbon ceramic brake pads
Due to its high performance and durability. Карбон-керамические тормозные колодки are mostly used in supercars and sportscars. Some of them are given below
- Lamborghini Aventador
- 488GTB Ferrari
- GT2 Porsche
- Model S Plaid – Tesla
Carbon Ceramic Brake Pads Vs Traditional Metal Brake Pads
A quick glance on the differences between углеродно-керамические тормозные колодки and Traditional metal brake pads приведены ниже:
- Карбон-керамические тормозные колодки are generally lighter and offer superior heat resistance in excessive breaking situations.
- With light weightiness, the handling of the machine becomes efficient when using углеродно-керамические тормозные колодки.
- Карбон-керамические тормозные колодки are considered to be expensive and is available only on high end automobiles. The advanced material used and the manufacturing cost adds up to the total cost of braking pad.
- Первоначальный укус углеродно-керамические тормозные колодки is lesser that that of metallic brake pads especially during cold weather.
- Металлические тормозные колодки are proved to be noisier than углеродно-керамические тормозные колодки and are heavy to handle.
- Карбон-керамические тормозные колодки are to be used in situations where excessive and frequent hard braking is required. It is to be used where the weight reduction is a critical parameter to increase the performance of the machine.
- Metallic brake pad is suitable for domestic driving where cost factor is crucial and where initial bite is required.
Closing remarks
For choosing тормозные колодки, defining context where the pad’s function is important. Upon comparison, it is evident that углеродно-керамические тормозные колодки are more superior and is used in high performance scenarios. Металлические тормозные колодки are used in everyday automobiles for its reduced cost; however, replacement poses an issue .
