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.
Disc brake construction
The brake rotor (disc) which rotates with the wheel, is clamped by
brake pads (friction material) fitted to the caliper from both
sides with pressure from the piston(s) (pressure mechanism) and
decelerates the disc rotation, thereby slowing down and stopping
the vehicle.
How disc brakes work
When the driver steps on the brake pedal, the power is amplified by
the brake booster (servo system) and changed into a hydraulic
pressure (oil-pressure) by the master cylinder. The pressure
reaches the brakes on the wheels via tubing filled with brake oil
(brake fluid). The delivered pressure pushes the pistons on the
brakes of the four wheels. The pistons in turn press the brake
pads, which are friction material, against the brake rotors which
rotate with the wheels. The pads clamp on the rotors from both
sides and decelerate the wheels, thereby slowing down and stopping
the vehicle.

Friction Materials
1, Friction Raw Material
2,Types of friction materials
*1 Sintered alloy: The phenomena where the particles of powder
material join together and turns into a solid substance by
pressurizing and fabricating the powder material and heating it at
temperatures below the melting point. Material that is not made by
melting metal, but instead by sintering metal powders is called
sintered alloy.
*2 C/C composite: Carbon fiber reinforced carbon composite. Carbon
composite material has been strengthened with carbon fiber. It is
extremely thermally stable and lightweight. This material is often
used for brake rotors and brake pads for aircraft and racing cars.
