Defining Organic Brake Pads
Organic brake pads are a type of brake pad predominantly made from natural materials. These pads do not contain asbestos, which was a staple in older brake pads but was phased out due to its health risks.
Instead, organic brake pads utilize materials like glass, rubber, carbon compounds, and sometimes even Kevlar. These materials are bound together with heat-resistant resins to create the brake pad.
Characteristics of Organic Brake Pads
One of the standout features of organic brake pads is their softer composition. This softness results in smoother braking, reducing the chances of abrupt stops. Furthermore, organic brake pads are known for their quiet operation, minimizing the squeaking or squealing noises often associated with braking.
Another significant characteristic is their eco-friendliness. Since they are made from natural materials, organic brake pads are more environmentally friendly than their semi-metallic or fully metallic counterparts. They produce less dust, which not only benefits the environment but also keeps the vehicle’s wheels cleaner.
Why the Shift to Organic?
The shift towards organic brake pads was primarily driven by health and environmental concerns. As the dangers of asbestos became more evident, the automotive industry sought alternatives that would be safe for both the mechanics working with them and the environment.
Organic brake pads emerged as the ideal solution, balancing performance with safety and sustainability.
What Are Organic Brake Pads Made Of?
Organic brake pads are primarily constructed from natural materials such as glass, rubber, and various resins. They are called “organic” because they primarily contain non-metallic materials, offering a more environmentally friendly alternative to traditional asbestos brake pads.
Primary Materials in Organic Brake Pads:
- Glass Fibers: These provide strength and structure to the brake pad, ensuring it can withstand the pressures of braking.
- Rubber: Rubber compounds in organic brake pads enhance flexibility and resilience, allowing the pads to return to their original shape after each brake application.
- Carbon Compounds: These compounds contribute to the brake pad’s heat resistance, ensuring they remain effective even under high temperatures.
- Kevlar: Known for its high tensile strength, Kevlar is sometimes added to enhance the pad’s durability and longevity.
- Resins: Heat-resistant resins are used to bind the various fibers and materials together, giving the brake pad its shape and consistency.
- Various Fillers: These can include other natural materials or minor amounts of metal to fine-tune the brake pad’s performance characteristics.
Binding Materials
To hold these fibers together and give the brake pad its shape and consistency, different types of heat-resistant resins are used. These resins ensure that the brake pads remain intact and functional even under high temperatures that result from the friction of braking.
Additional Ingredients
While the main components are natural fibers, some organic brake pads might incorporate minor amounts of metal to enhance their performance.
However, it’s crucial to note that the metal content in organic brake pads is significantly lower than in semi-metallic or fully metallic brake pads. This minimal metal inclusion ensures that the pads retain their primary characteristic of being “organic.”
Environmental Considerations
One of the standout features of organic brake pads is their environmental footprint. Given that they are predominantly made from renewable resources, organic brake pads are more environmentally friendly.
Their manufacturing process emits fewer pollutants, and the absence of harmful materials like asbestos makes them a safer choice for both the environment and the users.
Why the Emphasis on Organic Materials?
The shift towards organic materials in brake pads is not just a marketing gimmick. With increasing awareness about environmental sustainability and health concerns related to asbestos, there was a pressing need for a safer alternative.
Organic brake pads, with their natural composition, emerged as the answer, providing effective braking without compromising on safety or environmental impact.
Organic vs. Ceramic vs. Semi-Metallic Brake Pads, What’s The Difference In The Materials?
Brake pads, essential for vehicle safety, come in various materials, with organic, ceramic, and semi-metallic being the predominant types. Each material offers unique properties, influencing performance, longevity, and suitability for different driving conditions.
