3、es. Then introduced sedan anti-lock braking system in the vehicles location, analysis of the circuit ABS braking system structure, control relays, wheel speed sensors and actuators, where actuators are electro-hydraulic components, structure, complex, both contain hydraulic components, have received
4、 ECU control of electrical components, can effectively control each wheel hydraulic brake wheel cylinders increase, reduce or maintain, to prevent the wheels when braking Hugging, making the car get the best excellent braking effect. ABS actuator is actually controlled by the ECU of the brake pressure regulator device. Then on the disc (drum) brake system, vacuum brake booster and brake pedal assembly composition, inspection, assembly and adjustments of detail. Finally the micro-car brake syst
