II, About Disc Friction Brake Pads
1, Definition of Disc Friction Brake Pads

Disc Brake Pads

Brake rotors of disc brakes rotate with the wheels, and brake pads, which are fitted to the brake calipers, clamp on these rotors to stop or decelerate the wheels. The brake pads pushing against the rotors generate friction, which transforms kinetic energy into a thermal energy.


This thermal energy generates heat, but since the main components are exposed to the atmosphere, this heat can be diffused efficiently. This heat-dissipating property reduces brake fade, which is the phenomenon where braking performance is influenced by the heat. Another advantage of disc brakes is its resistance to water fade, which occurs when the water on the brakes significantly reduces braking force. When the vehicle is in motion, the rotor spins at high speeds and this rotational motion discharges the water from the rotors themselves, resulting in stable braking force.

Disc brakes are generally used in passenger cars, but due to their stable performance at higher speeds and resistance to brake fade, they are gradually spreading into the commercial vehicle segment, where drum brakes were traditionally chosen for their longer service life. There is increasing demand from customers for longer service life and higher quality, and Baiyun is committed to meeting them through further development of the disc brake’s reliability. There are two types of disc brakes.
The "opposed piston type disc brake" has pistons on both sides of the disc rotor, while the "floating type disc brake" has a piston on only one side. Floating caliper type disc brakes are also called sliding pin type disc brakes.

3, Brake Performance Of Disc Friction Brake Pads
1). Braking performance: friction coefficient (FF level: 0.35-0.45) braking force: braking force, braking sensitivity
2), wear resistance: wear rate (60,000-100,000km) wear resistance.(with driving habits, road conditions, climate, brake disc material (different models, brake disc material is different, the weight of the car is different)).
3). Comfort: whether there is noise, whether there is a sense of braking, whether it is smooth.
4). Thermal recession: whether it is heat resistant -- the degree of thermal recession.
5). Shear strength: whether it falls off, whether it is easy to break, the density, whether the density is balanced, whether there are bubbles and gaps.
Other items: whether damage brake disc, whether waterproof - water recession degree, whether environmental protection, and brake disc fitting degree.

4, Factors affecting product quality/performance of Disc Friction Brake Pads
1). Formula and materials:
a. What kind of materials are included in the recipe?Is the ratio of various materials in the formula scientific and reasonable?There are dozens of commonly used materials such as: Arron, copper fiber, ceramic fiber, carbon fiber, synthetic graphite, six titanium potassium acid whisker, powder nitrile, antimony sulfide, etc
b. Purity and quality of materials purchased by the company
2). Components:
The quality of the components used, such as the disc brake sheet's steel back and muffler, also affects the performance and quality of the entire brake pad.
3). Processing technology:
a. Control management and protection of materials and components.
b. Pressing effect of pressing process, pressing pressure, whether it is equal ratio pressing, pressing temperature and duration, etc.
c. Whether the heat treatment temperature and time are appropriate, and whether the grinding process is fine and standardized.
d. Procedures such as sandblasting and polishing, adhesive coating, marking and packaging, and control of semi-finished products and finished products
