What is the best material for brake pads?

Brake pads are not unfamiliar to anyone, and they need to be replaced when they are worn out, otherwise the safety risks are very high.

In the braking system of a car, brake pads are the most critical safety parts, and all brake effects are decisive for brake pads, so it is said that good brake pads are the protector of people and cars.

So some people have questions: what material brake pads are called good? There may be a lot of people will answer in the same breath “ceramic”, in fact, it is not, the next detailed explanation of the mystery for you.


Brake Pads

First of all, we need to understand the structure of brake lining.

Brake pads (brake lining) generally consist of steel plate, adhesive layer, heat insulation layer, friction material, (muffler).

The steel plate is painted to prevent rust, and the painting process uses SMT-4 furnace temperature tracker to detect the temperature distribution of the painting process to ensure quality.

The heat insulation layer is composed of materials that do not transfer heat, and the purpose is heat insulation.

The friction material is squeezed on the brake disc or drum to produce friction when braking, so as to achieve the purpose of vehicle deceleration and braking.

The construction diagram of brake pads

Next, it is important to know the classification of brake pads.

According to the different friction materials brake pads are divided into: metal type brake pads and carbon ceramic brake pads.

Among them, metal brake pads are divided into micro-metal brake pads and semi-metal brake pads, ceramic brake pads are classified as less metal, and carbon ceramic brake pads are used with carbon ceramic brake discs.

Finally, it is important to know the brake coefficient and grade of brake pads.

Friction coefficient: A parameter that indicates the friction efficiency of a brake pad.

The more sticky the pad is, the greater the resistance, the more sensitive the braking, but the worse the comfort and heat resistance, the lighter the pedal will nod, and the harder the pedal will burn.

High-temperature brake pads are those that can maintain the brake coefficient at higher temperatures, not necessarily the friction coefficient of high-temperature brake pads.

The grade of brake pads is expressed by two letters, the first one is to take 4 points between 0~600 (315.5 ℃) Fahrenheit to measure the coefficient of friction, if all can be in 0.35~0.45, then the low temperature grade of pads is F.

Then take 10 points between 600~1112 (600 ℃) Fahrenheit to measure the coefficient of friction, if it can also be between 0.35~0.45, the high temperature grade is also is F.

Brake Grade Classification

Now we know which grade ceramic brake pads belong to! Ceramic brake pads belong to FF class, which is moderate in the whole brake products.

Let me tell you: the coefficient of friction is just a reference, the brake pads have a lot to do with the friction material! For lighter vehicles, such as Japanese and Korean cars, ceramic brake pads are recommended; for heavier vehicles, such as American and German cars, micro-metal brake pads are recommended.

The material of micro-metal brake pads is more complicated and will be formulated according to the comfort level of the car. As shown in the figure below.

Micro-metal brake pad material

In fact, the best brake pads are not “ceramic brake pads”, but should be chosen according to the characteristics of your car.

There is no lack of the most expensive brake pads in the world, but there is the most suitable brake pad for you.

In the choice of brake pads must buy the brand, such as the market sold better: Philodex, Bosch, Brembo, Raybestos, Tymington, etc..

Now many miscellaneous brands labeled friction coefficient many are water, money saved on materials and processes, must be careful!So choose the best brake pads according to the type of car
