Brake Pad Materials.pptx

Brake pads are a crucial component in any vehicle's braking system. They are the replaceable friction pads that press against a vehicle's brake rotor, creating friction and slowing or stopping the vehicle.

There are several different materials used in brake pads, each with their own characteristics, benefits, and drawbacks. Ceramic, semi-metallic, organic, and low-metallic NAO brake pads are the most common types used in modern vehicles.

In this presentation, we will provide a comprehensive overview of the different brake pad materials, including their characteristics and benefits. We will also discuss how to choose the right brake pad for your vehicle and driving style, as well as provide tips on maintenance and replacement.

By the end of this presentation, you will have a better understanding of how brake pads work and what to look for when selecting new brake pads for your vehicle.

2. Brake pads are an important part of a vehicle’s braking system. Disc brakes rely on the calliper, brake pads, and rotor to function correctly. The brake pad sits inside a calliper that clamps down on the rotor. 2 Over the time, these Pads start wearing due to friction.

3. 3 Being able to stop quickly is much more important than acceleration! So picking the right brake pad is a vital part of any car’s modification process

4. There are several types of brake pads; Organic, Ceramic, Semi-Metallic, Non-Asbestos O rganic (NAO), Low-metallic NAO . and it’s important to know which type is best for your vehicle. 4

5. Brake pads are judged by several factors; P erformance (how well they stop), D urability (how long they last), B rake dust, Noise. 5 Organic Originally, these pads were made with asbestos but were replaced with carbon, fibreglass , rubber, and Kevlar compounds due to their harmful nature. Ceramic These brake pads use a mixture of copper filings and ceramic compounds (the kind you make pottery with). Semi-Metallic These brake pads use a percentage of metal filings anywhere from 20%-80% in their composition . These include iron, steel, and copper mixed with binders like graphite.

6. 6 Ceramic Ceramic fibers: 30-35% Copper fibers: 3-30% Iron powder: 10-15% Fillers & binders: 25-35% Lubricants & abrasives: 5-10% Pros of ceramic brake pads: Better performance at high-speed braking. Quieter operation due to less metal content. Reduced brake dust on wheels . Longer lifespan. Cons of ceramic brake pads: Expensive manufacturing. Less effective at low temperatures. Harder on brake rotors, causing increased wear. Potential for more noise and vibration R ecommended to customers who want to enjoy the look of cleaner rims free of black brake dust.

7. 7 Organic Organic fibers: 20-60% Rubber : 10-30 % Filler materials (e.g., carbon, Kevlar) : 10-30 % Resins and adhesives: 5-10 % . Experience superior stopping power and reliability with MTB organic brake pads. MTB Organic Pads: Superior stopping power and durability. Quieter ride. Ideal for safety and performance. Consistent braking in all conditions. Compatible with many mountain bikes and b raking systems

8. 8 Semi-Metallic Metal fibers: 30-65 % Non-metallic materials: 20-40 % Fillers and binders: 5-30 % Cons : Produces more brake dust. Can be noisier. Can wear down brake rotors faster. Not suitable for all vehicles or driving conditions. Pros: Better stopping power. More durable than organic brake pads. Performs well in heavy-load conditions. More affordable than ceramic brake pads.
