How many kilometers can brake pads be replaced
Brake pads can generally be replaced before driving for 30000 to 50000 kilometers, and after driving for 60000 to 100000 kilometers. This replacement cycle is determined based on the general service life of the brake pads, but the specific replacement time will also be affected by factors such as the road conditions of the vehicle, personal driving habits, and the thickness of the brake pads. Therefore, the actual replacement cycle may vary. To ensure driving safety, it is recommended that car owners regularly check the thickness of the brake pads. Once the thickness of the brake pads is less than 3 millimeters, they should be replaced in a timely manner. In addition, the brake pad warning light on the vehicle dashboard is also an important reference indicator. When the brake pad warning light is on, it indicates that the brake pads have been worn to a certain extent and need to be checked in advance and may need to be replaced.
Transmission of braking force
The force exerted by the brake caliper piston on the brake pads is called the Pedal Force. The force exerted by the driver on the brake pedal is amplified by the lever of the pedal mechanism, and then amplified by the vacuum power boost using the principle of vacuum pressure difference to push the brake master cylinder. The hydraulic pressure emitted by the brake master cylinder utilizes the incompressible power transmission effect of the liquid, which is transmitted to each cylinder through the brake oil pipe. The pressure is amplified using the "Pascal principle" to push the piston of the cylinder to apply force to the brake pads. Pascal's Law refers to the principle that the pressure of a liquid at any position inside a closed container is the same.
Pressure is obtained by dividing the applied force by the area under force. When the pressure is equal, we can achieve the effect of power amplification by changing the ratio of the applied and applied force areas (P1=F1/A1=F2/A2=P2). When used in brake systems, the ratio of master cylinder to slave cylinder pressure is the ratio of master cylinder piston area to slave cylinder piston area.
