Nowadays,With the advancement of the car-making process, the engine horsepower
has increased. In the era of speed pursuit, the brake system is particularly important.
This time, we will talk about the important elements in the brake system: Brake Pad.
About the brake pad,people usually will ask :how can i know which one is good for
me ? what time should i change it ? is ok to add the oil on it ? what material is more
good for my motorcycle ?
Today,we will show you the answer for it.
1.How many kind of material for brake pad?
5 kinds, according to the material are asbestos, non-asbestos (NAO), semi-metal
sintered (SEMI-METALLIC), metal sintered (MMC), composite
material(CONSTITUENT).
material(CONSTITUENT).
Asbestos produces toxic gases at high temperatures; non-asbestos is mainly made
of glass fiber. The advantages of low cost and easy material availability are quite
attractive to manufacturers, but they are not resistant to high temperatures and
are prone to heat exhaustion, which discourages consumers. In order to solve
the problem of NAO, the manufacturer developed a composite material of the
brake skin, using a stronger material, such as KEVLAR, carbon fiber, ceramic, has
a better braking force.

Semi-metal sintering is made of metal and steel, copper fiber, which has better
high temperature stability than non-asbestos, but the wear is relatively poor;
metal sintering is made by metal powder through high temperature and high
pressure sintering. Strong braking force, but the attacking power of the disc is
relatively strong. When it is "ultra-high temperature", it is easy to produce
carbides and the braking force is weakened.

2.What does that means about HH on the brake pad?
Represents a coefficient of friction greater than 0.55 at 0-680 °C. The coefficient
of friction coefficient is divided into eight steps from EE, EF, FE, FF, FG, GF,
GG, HH from low to high. The first letter represents the friction coefficient
at room temperature (0-250 ° C), and the second letter represents The friction
coefficient of high temperature (250-680 °C), the friction coefficient of each
letter is: E=0.25≦μ≦0.35, F=0.35≦μ≦0.45, G=0.45≦μ≦0.55, H=μ≧0.55.

3.What is the function of the groove of the brake pad?
Eliminate dust, increase heat dissipation, and facilitate identification. When the
brake car and the disc are rubbed, some dust will be generated. If it is attached
to the disc, it will cause damage. Therefore, grooves are designed on the wagon
to facilitate dust discharge and good heat function. Some grooves are designed
as indicator lines, just like the safety indicator line of the tire. When the groove
is finished, it means the brake shoe needs to be replaced.
