The document discusses various types of brake pads used in vehicles, highlighting their composition, performance, and suitability for different conditions. It categorizes brake pads into organic, ceramic, semi-metallic, and non-asbestos organic, detailing their advantages and disadvantages. Proper selection of brake pads is crucial for vehicle safety and performance, particularly in modifying cars.

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.

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;
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.
