Braking force transfer


Pedal Force The Force exerted by the piston of the brake caliper on the brake pad is called Pedal Force. After the force of the driver stepping on the brake pedal is amplified by the lever of the pedal mechanism, the force is amplified by the vacuum power boost using the principle of vacuum pressure difference and used to push the brake master pump. The hydraulic pressure issued by the brake main pump is transferred to the sub-pump through the brake pipe by the liquid incompressible power transmission effect, and the pressure is amplified by "Pascal's principle" to push the piston of the sub-pump to exert force on the brake pad. Pascal's Law states that the pressure of a liquid is the same anywhere in a closed container.


The pressure is obtained by dividing the applied force by the stressed area. If the pressure is equal, we can use the change of the ratio of applied and stressed area to achieve the effect of dynamic amplification (P1=F1/A1=F2/A2=P2). For braking systems, the ratio of the total pump to the sub-pump pressure is the ratio of the total pump piston area to the sub-pump piston area.
