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. o Brake pads are an important
part of a vehicle’s braking
system.
o Disc brakes rely on the calliper,
brake pads, and rotor to function
correctly.
o The brake pad sits inside a calliper
that clamps down on the
rotor.

Over the time, these Pads start wearing due to friction.

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;
i. Organic,
ii. Ceramic,
iii. Semi-Metallic,
iv. Non-Asbestos Organic (NAO),
v. Low-metallic NAO.
and it’s important to know which type is best for your vehicle.

5. Brake pads are judged by
several factors;
 Performance (how well they stop),
 Durability (how long they last),
 Brake dust,
 Noise.

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.

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

Organic
 Organic fibers: 20-
60%
 Rubber:
10-30%
 Filler materials (e.g., carbon, Kevlar): 10-
30%
 Resins and adhesives: 5-
10%

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 braking 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.
