Ceramic vs Semi-Metallic Brake Pads: What’s the Difference?

When choosing brake pads for your vehicle, various options are available. Two popular choices among car owners are ceramic and semi-metallic brake pads. Both options have unique features and benefits, making it essential to understand their differences before deciding. In this article, we will compare Ceramic vs Semi-Metallic Brake Pads, delving into their composition, performance characteristics, durability, noise levels, and other crucial factors that can help you make an informed choice for your braking needs. Whether you are looking for better stopping power or reduced noise levels during braking, understanding the distinctions between ceramic and semi-metallic brake pads will aid in selecting the most suitable option for your vehicle’s requirements.

A Brief Overview of Brake Pads Material

Brake pads are an integral part of a vehicle’s braking system, which converts kinetic energy into heat by creating friction against the rotor. The material used for brake pads is crucial in determining their performance and durability. There are common brake pad materials available, each with unique characteristics.

Ceramic vs Semi-Metallic Brake Pads

Semi-Metallic Brake Pads

Semi-metallic brake pads have become the standard choice for most cars currently on the market. Initially introduced in the 1960s, these brake pads were designed using metallic and non-metallic materials. The metallic components comprise a significant portion of the place, typically comprising anywhere from 30 to 70 metals. These metals commonly include iron, copper, steel, and other elements.

The non-metallic filler materials make up the remaining composition of the brake pad. These materials are responsible for enhancing the performance and durability of the place. They can include resins, rubber compounds, or even kevlar fibers.

Ceramic-Metallic Brake Pads

In the 1980s, a breakthrough occurred in brake technology with the introduction of ceramic brake pads. Since then, these pads have gained significant popularity among drivers worldwide. Ceramic brake pads are meticulously crafted using a durable ceramic compound often blended with other reinforcing materials. This ingenious combination enhances friction levels and heat management capabilities, producing exceptional braking performance even during intense and prolonged braking situations.

In the past, ceramic brake pads were made with a significant amount of copper threads for their beneficial properties. As of 2015, the Environmental Protection Agency (EPA) has established regulations requiring manufacturers to reduce the copper content in brake pads. By 2021, the copper content in brake pads must be lowered to less than 5 percent by weight. This reduction aims to minimize the release of harmful copper particles into waterways during normal braking operations.

EPA has set an even more stringent target for 2025 – a maximum of only 0.5 percent copper content in brake pads by weight. These regulations align with efforts to protect aquatic life and preserve delicate ecosystems that may be adversely affected by excessive copper exposure.

Organic Brake Pads

Organic brake pads, also known as non-asbestos organic (NAO) brake pads, were developed as a safer alternative to asbestos-based brake pads. In the 1990s, asbestos-based brake pads were in vehicles manufactured before 1974. Organic brake pads are made from materials and fibers such as rubber and carbon compounds. These non-metallic brake pads are considered the softest among all types. They provide smooth braking performance and generate less noise compared to other options.

Organic brake pads have gained popularity due to their environmentally-friendly nature, as they do not contain harmful metallic components like copper or steel particles. This makes them less damaging to the environment through reduced dusting and run-off during braking. In addition, they produce less wear on rotors, leading to longer rotor life.

Performance & Durability

With an emphasis on performance, these semi-metallic brake pads offer superior braking efficiency and increased responsiveness, minimizing stopping distances for enhanced safety on the road. Including metal fibers ensure effective heat dissipation, reducing the risk of brake fade even during prolonged or heavy braking.

Durability is a crucial feature of our semi-metallic brake pads, as they are built to withstand high temperatures and wear-and-tear associated with aggressive driving or frequent stop-and-go traffic situations. The robust construction of these brake pads allows them to maintain their performance level over an extended period without compromising reliability.

In terms of performance, ceramic-metallic brake pads offer exceptional stopping power. They have a high coefficient of friction, meaning they grip the rotor tightly and bring your vehicle to a quick halt. This is particularly crucial in emergencies where you need immediate braking force.

These brake pads provide excellent heat dissipation capabilities. The combination of ceramics and metal allows for efficient heat transfer away from the braking system, preventing overheating and reducing the risk of brake fade.

When durable, ceramic-metallic brake pads excel as well. Their composition makes them more wear-resistant than traditional organic or semi-metallic pads. This means they can withstand heavy use over extended periods without compromising effectiveness.

Noise & Dust Level

Ceramic brake pads are usually quieter compared to semi-metallic brake pads. This is because ceramic pads are composed of a softer material that provides better sound insulation, resulting in less noise during braking. In comparison, semi-metallic pads contain metal particles within the friction material, which can generate more noise when pressed against the rotor.  

Ceramic brake pads produce significantly less brake dust than semi-metallic brake pads. The ceramic compound in these pads generates finer particles that do not stick to wheels as quickly. Therefore, vehicles equipped with ceramic brake pads require less frequent cleaning and maintenance than semi-metallic ones. Conversely, semi-metallic brake pads tend to create more coarse dust due to the presence of metal components within their construction, leading to increased buildup on wheels and requiring regular cleaning efforts.

Price

Ceramic brake pads tend to be more expensive compared to semi-metallic brake pads. This is primarily because ceramics are made from composite materials containing ceramic fibers, copper fibers, and various fillers. The manufacturing process of producing ceramic pads also adds to their higher cost.

Semi-Metallic Brake Pads are composed of iron, copper, and other metals, making them more affordable than ceramic brake pads. Due to their metallic components, they excel in heat dissipation, making them suitable for high-performance vehicles that frequently undergo intense braking.
