Generally speaking, steel plates, adhesive insulation layers and friction blocks are the main components of brake pads. According to the different materials, brake pads can be divided into many different types, including asbestos brake pads that have been basically eliminated, low-metal brake pads, semi-metal brake pads, NAO formula brake pads, ceramic brake pads, etc. Among them, ceramic brake pads with highly recognized performance have been widely used in recent years. Ceramic brake pads have more advantages than traditional brake pads. There are several essential key components in the composition of brake pads. In order to meet different driving needs, they are made of a variety of different materials. The following is a detailed analysis of the components: First, the components of the brake pads. Friction material: This material is the part of the brake pad that comes in direct contact with the brake rotor.Through special customization, it can withstand high temperatures and provide consistent friction. Backing Plate: It is the metal plate that supports the friction material.It also provides a solid foundation to subsequently transfer the braking force from the caliper to the friction material. Bonding Layer: The method by which the friction material is bonded to the backing plate. This method can withstand heat and pressure without weakening. Shims: It reduces noise and vibration, usually a thin layer attached to the backing plate. It is usually made of rubber-coated steel material, and sometimes other damping materials. Optional Wear Indicator: Places inside some shims and signals when they need to be replaced, either by a squealing sound or electronically through a dashboard alarm.Materials used in brake pads 1. Semi-metallic brake pads: Composition: Synthetic fillers and resins combined with 30-65% metals such as steel, iron, and copper. Advantages: Durable, good heat dissipation. Suitable for higher performance vehicles. Disadvantages: Noisier, wears rotors faster. Pollutes the environment and produces more brake dust. 2. Ceramic brake pads: Composition: Very dense ceramic material with fibers (fine copper) embedded inside. Pros: Long service life, less wear and tear on the rotor. Performance is stable over a wide temperature range. Low dust and quiet. Cons: It is more expensive. Not suitable for ultra-high performance vehicles or heavy-duty applications.
3. Non-asbestos organic - NAO brake pads:
Ingredients: Fibers made of materials such as glass, rubber, Kevlar or carbon are bonded together with resin.
Advantages:
Soft, quiet braking feel.
Asbestos-free and more environmentally friendly.
Disadvantages:
Poor durability.
Poor environmental pollution and more dust.
4. Low metal brake pads:
Composition: organic materials mixed with a small amount of metal materials such as copper or steel.
Advantages:
Improve its braking performance.
Good heat dissipation.
Disadvantages:
Relatively loud.
Will produce some moderate dust.
Special materials
Carbon ceramics: can be used in racing or high-performance vehicles, with excellent lightness and heat resistance.
Sintered metals: commonly used in off-road vehicles and motorcycles, with durability in harsh conditions.
